I did some pumping about 20 years ago with homemade cups from Walmart.  Decided to go with properly made ones this time around.  Much more comfortable.  I did a little pumping today.  The manual seems to indicate a sort of pulsing method - pump up, let sit for a few seconds, then depressurize and repeat.  I used to pump them up and let them sit for as long as I could stand it.  Did some of that today and have the familiar red/purple marks where the cups were.  When I lived alone, this wasn't an issue, but these days, it is.  Am I using too much pressure?  I've seen some pictures here and the marks aren't as obvious.
