inflation amounts

i am wondering there is any rules of thumb as to how much a first time person can add if they are regulary 15inches around after a vac pump session?

Start slow with 500ml. Then when you are comfortable add another 500ml.
Put some time between your infusions. Wait at least 24 hours between infusions.
After you do this a couple of times, you will know how far you can go.

I always start with 1L (I use D5, Saline and D5N9 can really sting for me)
I can now add 2L at a time after the first Liter.
This has taken a year to accomplish.

I regularly pumped to 15" round when I first infused. I took 1 liter my first infusion. and 15" = 38.1 cm

we can do some quick algebra (while high), here goes:
Circumference = 2πr ; circ = 38.1 cm which gives a radius = 6.0638cm

Volume = 4/3 X π X r^3
volume = 4 / 3 * 3.14159 * 222.9639 = 933.95 ml volume.
(want to know how many times I've done this calculation? enough that I can do the math while high)

so, if you can pump up to 15" you can take roughly a liter of infusion volume. Roughly.
Take as much as you feel you can: If it's drippin' you're sippin'.

Cheers,
Russ.

High or not mRuss, that math is way over my education. So thanks, This helps alot with planning future inflation
