Is this method of measurement consistent?

So I got this problem with measuring after hanging and its been so inconsistent.

I always begin hanging with 10 mins (0.5kg) just to measure my before BPFSL so I can measure it afterwards too.

I also got a fish hook like device where I can actually measure the pulling power so its always consistent.

The problem/question is: is it consistent?
Because yesterday I had a pulling power what I call 75 + 1 bar after 10 mins hanging with 0.5kg. The measurement was 17.5/17.6cm

Now today Ive tried the exact same pulling power (75 + 1) but I measured 17.4cm.

The difference is that yesterday I could not have pulled much harder then 75 + 1 bar. Today 75 + 1 bar didnt feel very hard to pull so I could easily pull to 75 + 2/3 bars and then I got like a 17.5/17.6cm measurement. So on this day my dick is much more flexible before a workout then a other day. And maybe next time its reversed.

Should I ignore the pulling power and just pull as hard as I can and then its consistent or is the pull power (if it always the same pull power) more consistent?

Im getting some weird measurements now and I need to get a better track of my stats.

Thanks!

Never “pull as hard as you can” because you’ll break your dick.

And what you’ll end up doing in the long run is strengthening your penis so it becomes harder to get gains.

Using the same force attached in the same way is as consistent as you can make it, from a force perspective. There is also the ruler or measuring side of things but that is a different conversation. There will be small variations up and down between days so don’t worry about that. You need to be aware of the overall trend, if that is going up, down or staying the same.

Pulling as hard as you can doesn’t give you consistency.

But I can show you my measurements in the next 5 to 6 sessions I do 2 days on 2 days off 1 month total and 3 months decon. The measurements are a joke. It goes from 17.2cm BPFSL to 17.5cm before a workout and after a workout the differences can be 0.2-0.3cm too.

In general, I believe that differences below 0.5cm are not something I’d consider for a consistent tracking
