I do:
First 10min warming up in a hot bath.
8 min pumping
5 min rest with jelqing and stretchting

I have a full erection, do it with full suction an do kegels while pumping.
I have a Bathmate X40 Hydromax Extreme.
Gained 4mm in girth past 9 months...
Same here I do pretty much a different routine every pump and I've been pumping quite religiously since May 2018 (I had pumped off and on in the past 10 years, but never really kept up with it like this past year). It's not that I don't want to follow a specific, same routine every time. It's that sometimes I let time pass and my number of minutes in the tube miss my mark. For instance:
I use a rice sock thing to warm up for 12-20 minutes, depends on how much heat the thing has stored in it.
then wet jelq for anywhere from 5-10 minutes, depends on how horny I am and how good my EQ is that day.
Then in the tube, usually always low pressure 3-4hg in my 2" cylinder for 4-6 minutes.
A few minutes of jelqing and massaging/jerking to maintain EQ
Then I have two "rice sock donuts" that I sewed to completely encircle my 1.75" cylinder, and I use them and the smaller cylinder for probably 10-12 minutes.
Then jelqs and jerking.
And then my imagination runs quite wild! Like the other day I did: 5min 2", 10min 1.75", 5min 2", 10min 1.75", 5min 2" to end. Pretty fun and varied 35 minute pump session.
Once I did minutes in increments of 4, 6, 8, 10, 12 to get to 40 minutes in the tube. Sometimes I don't throw the 2" tube on in the middle or even end of my routine. Sometimes I just use the 1.75" tube.
I keep a stopwatch going every session and note exact minutes and which tube used throughout. I've been logging all this information into a spreadsheet and actually need to turn it into data. I also write down what it's like at the end.
What am I looking for?? Why am I spending extra time and steps while pumping? Why not just throw the tube on and let it rip (which is something I would love to do!!)?
Because some pumps are wayyyyyyy better than others. Some I pack more, some less. Some I get red spots, some I get edema, some I get both, some I get neither. Within this year of information I've collected there is likely some "golden formula" for me that equals zero red spots and edema, the fullest pump I can achieve and within the optimum amount of time.
I deal with data for a living and making observations and experimentation. It's just all so interesting, the variety of pump quality and outcomes from day to day. I'm close to collating all this information and plan to run some analysis on it all. I will update here in the near future with my findings if anyone cares

Happy pumping to all!
