Of course this won't be a scientifically reliable survey, but the inconsistencies will at least be consistent. Tim (or whoever) will t least be able to say "We asked the same sample size for both positive and negative replies, and THIS is the result" instead of just "XXX reported a problem."
Water vs Heat: Mine failed after a whole day's riding in the rain, some of it really torrential, followed by a night parked in the rain, followed by a damn good thrash up the Stelvio pass (not rhyming slang) - when the bikes I was with were all running very hot. So my failure could be down to water, heat, or both, or neither. There was no sign of damage when I hacked apart the broken unit.
(I haven't taped up my ventilation holes, but the unit now sits in a big lump of silicon grease. Even when the well fills with water, it's not getting anywhere near the seal at the bottom. Lor donly knows if this will prevent another failure, but I carry a spar ewith me everywher I go now just in case.)
