How much do you gain after your session....

Just curious,if I am on an even track.
If I pump at 4hg,I only get up to 1/8 of an inch in girth.
If I pump at 5hg,I get fluid build up, but I have done condom pumping 2 times now(thanks to advocet for recommending it).Afterwards I am 2/8 of an inch bigger(in girth) w/ no noticable donut affect.I have pumped plenty of times at 5hg without the condoms,but anything over 2 sets of 10 is followed by the donut affect,so the measurements were probably distorted abit.

It is noticably bigger,but not by much. But its a start.I am just wondering if it varies alot,or if I am either on the lucky side,unlucky side or average side.

This will vary depending on your length of experiece and time of your pump sessions. I have been doing this a long time and will have anywhere from a 1/2 to 1 hour long pump session and will gain about 1/4 inch length and 1/2 inch girth. But when you just start out, just doing one or two ten minute sets, your gains will be less and I would say you are right on target with what you are seeing.

As you gain more and more experience and are able to spend longer times in the tube, not only will your immediate gains become greater, they will last much longer. I would say you are right on target. Keep avoiding the donut effect and be patient. You can also try doing shorter pump sets of say 6-8 minutes with jelqing or massage inbetween and perhaps that way you can work up to 3 or 4 pump sets with no donut effect.
