If your chain jumps to other gears, you've got derailleur adjustment problems and similar. Riding style shouldn't come into it.
I agree that the sideplates of the chain would likely encounter the pins if the teeth on the chainring are worn. But I've just closley inspected what happens on the FG I am building, and with a Shimano 42T ring with a seven-speed chain, the sideplates come close, but don't touch the pins. I don't disagree that a non-ramped and pinned ring would be ideal, but then I'm a guy who built up another FG with a Biopace ring and *never* had a chain drop, even at 120-plus rpm, and plenty of climbing... and people said that couldn't be done.
