@physlink guess I'm not really sure of a specific volume. Haven't really been measuring the output. I saw another post where the fella mentioned that there really is no leakage while sitting or lying down (sleeping) but as soon as you rise, the leaking begins. If I've been on the computer for an hour or so, when I stand up (and head for the bathroom) I'll pass a fair amount (maybe 150ml or so) but just guessing.
I guess the bottom line is, I leak continuously if not sitting or laying down. I've tried running with one of these pads in my shorts. It works I guess, but pretty uncomfortable. Biking is a different story. I try to arrange a pad so it collects any leaking but it's pretty difficult while sitting on a bike seat. Also, bike acts kind of like putting a cork in the bottle... Guess it's pushing up against things (bladder neck/urethra) and once I dismount I can pass quite a volume depending on how long I've been on the bike.
So, sorry to ramble, but guess I'm not really sure how to answer your question, I really don't have a very accurate way to measure my output. Maybe just say several (2-4) pads a day depending on how much I drink and how much I sit.
As I said, sorry to ramble, I'm new to this forum thing, have never participated in a forum before.
