I find that I am very sensitive to vacuum forces and time. If I go over a certain amount it can begin to crash my EQ. If I go way over it, instant crash. The great thing about the water pump is mine is set at 4 in hg, so I know I won’t exceed that when water or air pumping. The problem for me when water pumping without a gauge, I can easily go too high and crash my EQ, so this prevents it.
Just practice with the hand pump and fluid trap first so you see how you have to position everything to prevent water getting past it. Once you have that down, then move to the electric. I think you may end up doing all water pumping, really I think its more “bang for the buck”.
I was just reviewing some previous notes of mine and I found with water, 5 in hg for 10 minutes was a baseline. I could use either 5 or 6 in hg for a baseline at 10 minutes, and it would allow me to recover from over training. However, what really surprised me was that my EQ would at first improve at that level, then slowly drop. At first I thought it was over training but when I took time off, it dropped further. What I found was that if I bumped it up to 7 or 8 for a minute or two out of that 10 minute time, EQ would jump back up! So, my discovery was that my EQ had been dropping from UNDER stimulation!
So what I found was 5-6 was a recovery mode, 7-8 was stimulation mode. 7-8 too long crashed EQ and time off would return it. Time off or “active recovery” time at 5-6 in hg. So I found if I cycled from 5-6 in hg for 10 minutes, and when EQ started to drop, to add in a minute or two of 7-8…I was cycling at fairly high EQ. Problem was my skin couldn’t take it and was getting too many capillary ruptures and stress eczema was kicking in. PLUS, I think I wasn’t seeing any gains.
So, I have dropped down to lower vacuum levels and longer time. It seems 4 in hg seems to be doing better for me, but still experimenting on time and frequency. I might try throwing in 6 in hg for 2-4 30 second cycles to see. I do think that you have to be careful with higher vacuum levels because what happens is at first you see gains, but then they stop and you are stuck there. I do think its probably better for long term slow steady gains if you can keep it lower vacuum and just keep at it.
Anyway, thought I would share that.
