Around here, a ride with 5,000' of climbing means it has a hundred 50' hills, which does introduce some difficulty, but is not exactly the same as climbing one 5,000' climb in the middle of the ride, either. Or, if I include all the little bumps in the chip seal, my normal rides all have about 20,000' of climbing.
I mentioned this earlier.

I often get higher elevation gain in rwgps then any other method, and never lower. I've just gotten into my head what rwgps numbers feel like when I ride them.

Recently I did an out and back and the last few miles were showing the right zigzag pattern but all at 150 ft elevation higher than the matching part in the beginning. Obviously can't be.
