The potency of specimens varies greatly, so you usually can't be sure whether you're in for a mellow ride or a rollercoaster. I'd think the logical solution would be to take less than the full dose, say 15 inches of cactus, and if it's not as strong as you'd like by the third hour, take another x inches.
Of course, re-ingesting when you're already tripping isn't nice. I only have experience with reducing it to tea, usually a larger quantity than necessary, and I wouldn't want to have to choke that stuff down again. I'm going to try reducing 24 inches to powder with a coffee grinder soon (or something less expensive - any recommendations?) and I'm thinking of doing exactly what I said above; I want a strong trip, but I'll be in public so I'd rather it wasn't 'breakthrough', something in the realm of 450 - 550mLs would be ideal. I figure powder shouldn't be that bad if it's frozen and followed immediately with strong orange and mango juice + sugar + lemon.
So, as far as guaging strength goes, I don't see why you wouldn't redose every time to be safe? Unless you don't mind getting spontaneously blasted into outer space, which is viable too.
