That is my understanding and experience (wheelies in 2013 broke our chains sometimes), if I'm not completely right, sorry.

A way you can help prevent it is by switching to #35 chain, but honestly, just bring 5 or so spare chain lengths to competition (just in case).
Interesting. I believe your empirical evidence for sure, and we always bring an extra 25ft spool of chain and dozens of master links! Cheap insurance...
