7cm packed and just barely hit 17.8cm IPL! New record after new record means I definitely found my groove.

I think the new pumping method of starting at -8”Hg and letting it relax works well in combination with gprent’s linear routine

How much total time in the pump?

20mins total if I finish at -6”Hg or 25 mins if I go to -7”Hg. Basically 5 mins per pressure level starting at -3”Hg. Essentially a session looks like:

Pump to -7 or 8”Hg. Over 2-3 mins or so it falls to ~-3”Hg as tissues expand.
At the 5 minute mark, pump to -4.
At the 10 minute mark, pump to -5.
At the 15 minute mark, pump to -6.
At the 20 minute mark, finished.

For each 5 mins, apart from the first, if the pressure drops below the target I pump back to the target (eg I maintain the target pressure).

From the same authors as the previous paper which stated -200mmHg was the ideal pumping pressure, this paper investigates the ideal pumping regimen. Again, this is a rehabilitation focused publication, though there are mentions of length.

Using the ideal pressure, they found that durations over 4mins continuous application resulted in plateaued length. Only detrimental effects occurred past this. They also determined that a 5on-2off-5on (minutes) regimen provided the best therapy.

Again, these results seem to somewhat align with gprent’s linear routine; each pressure stage is held for 5mins so we never overly "plateau". At each new stage we enable more expansion. In a way, this reminds me of Kyrpa and Tutt’s stress-relaxation methodology for length.

So in that testing they did not test past 10 minutes. So we don’t know what the optimal length of time in the tube is just that releasing the pressure to bring in new blood incrementally was better for rehabilitation. gprent reported that maximal length in the tube is achieved at 30 minutes, once conditioned.

Have you observed when the gains in length in the tube occur during a session? I know that I was gaining additional length in the tube past 20 minutes.

I have seen an increase in IPL going from 20 to 25 minutes under constant pressure. I have yet to go longer using gprent’s linear regimen. I haven’t checked measurements during a session, but I think I’ll give it a go next time and report back - maybe at 5 minute intervals for now.

Last week was busy enough that I decided upon a 1 week break. Noticed over the week that my flaccid is looking bigger on average, which is nice. Think this is the pump doing its thing. I’ll be happy if this trend keeps going.

Aiming for 4x sessions this week, so lets see how it all goes.

Brief comment on an observation:

The max IPL can increase depending on how hard the tube is pushed into your pevlis when first depressurising the cylinder. This likely also affect the packed height, though is far more tricky to measure. While I do not think this is some “magic method” to get a little more out of a pump, I feel that this might be a way to reduce the variances I see in IPL and packed height - sort of like how BPEL is used vs NBPEL. Note that my method up until now has been to lightly push the tube on my pelvis before depressurising (just enough to create the seal).

About this, I feel like the dick has a defensive mechanism after heavy PE sessions: pulling up and turtling in, similar to testicles shrinking inward. OK, maybe not, but it’s strange how your dick can look shorter during PE yet longer and heavier about a week after.

Right now looks like it may be a 3 session week rather than the intended 4, but I’ll try get it done.

I think this is the case. Noticed this week I am right back to a smaller state after resuming pumping - though there are some moments where it does look bigger again (just the natural flow of things I guess).

The real test will be in a few months time when I have a longer break (around Christmas).

Only completed 3 session in the end, though not because that’s all I could manage.

I have noticed over this week that immediately after a session, when I exit the tube, there is a patch of very dark blue/purple “brusing” on the right side of my shaft (slightly reaching round to the CS and about 4-5 cm long). It mostly fades over a few 10s of minutes and is completely gone by the time I wake the following morning. I see or feel no other negative effects apart from the usual petechiae.

So I decided to not do a 4th session and to consider how to progress. I am currently doing gprent’s linear routine starting at -3”Hg to -8”Hg over 30mins continuously. Since I am definitely seeing gains (official measurement isn’t until month end), I need to determine whether to continue or not.

I will consider this over tomorrow. If anyone has experienced similar, I’d love to hear your feedback and advice.

The Fix

I will try a few this over the course of this week to see if it reduces this “brusing” effect.

Setup:
Session was as follows: Started at -3”Hg and every 5 minutes reduced pressure 1”Hg. Ended session at -8”Hg after 30 minutes.
The difference is that after each 5 minute segment, I fully depressurised for 2 minutes (remaining in the tube).

Observations:
No sign of the “brusing” and generally less discoloration overall. Slightly less edema. Same IPL and similar packed height.
Right now this seems like an ideal way to fix the issue as there are no apparent drawbacks, apart from needing an extra 12 minutes for a sesssion. I’ll try this method for the remainder of the week to confirm.

Successful week completed. Managed 3 nights and 1 morning session (more on that shortly). Possibly one more tomorrow night!

Trying out the 2 minutes break between pressure stages has completely reduced any brusing and decreased overall discoloration. There is also slightly less edema. So an overall win for that technique! I will keep it in the routine going forward.

Last session I tried my total man heat pad, rather than my usual heat pad. I’ve yet to draw a conclusion but I think that the FIR is being absorbed by the acrylic (so heating that up rather than tissue). I’ll give it a few more tries and try compare.

Last, as hinted at the start, I’ve decided to incorporate morning sessions. These will be different than the night sessions. 5 mins at -8”Hg, 2 mins break, 5 mins at -8”Hg and finished (12 mins total). Basically following the protocol in the papers I linked earlier in this journal. These sessions will be on the morning after each night session.

And that about wraps things up.

I realise that it has been a little over a year since I started this journal. Unfortunately it is not 100% possible to compare measurements to back then, since I did not have a consistent measurement scheme (for length that is). My first mention of BPEL in this thread claims I was 17.1cm (IndyMan - Indyman’s Journey). While I never posted it, my MSEG has always been around 12/12.1 cm.

I decided to measure last night, I am officially 17.0cm by 12.3cm. While not a massive increase, it is still an increase. I feel that the pump is definitely helping me gain this last month or two, so will continue this routine for sometime. My goal for the next month is to increase the number of sessions per week (both morning and evening ones).

Commenting back on my FIR heatpad observation. I am now convinced that there is no FIR penetrating the acrylic. Attached is a transmission profile for some generic “acrylic”. Basically all the usual materials absorb light past 5 microns. The FIR we want is at around 10 microns (deepest penetration depth).. so not happening. That said, I feel that it does heat the tube more effectively than a regular heat pad, so will still use it going forward.

Just posting as I seemingly vanished…

I took one week break due to some high workload, plus I felt I needed one. Unfortunately when I wanted to restart this week I found I had either a minor UTI or something else that was bothering me, so decided to wait it out. I’m all good now but will restart again properly next week.
