Each year we have used the same chains for two regionals, Atlanta, several off season season events, and quite a bit of testing with zero problems. This has been the case over the last 4 seasons and our 2008, 2009, and this years robot all have the original chains from build season.

I completely agree with you and think this is true, so long as the chassis is extremely rigid. If the chassis has any amount of flex the looser chains could easily pop off of the sprockets. I know 233 uses box extrusion for the chassis which must make for an incredibly rigid setup not allowing for any misalignment.
