Totally agree with the 'accidental sandbagger' category, or whatever you want to call it. I think that's kind of what me and @BurningLegs were last season in ZRL C - despite hitting the sprints and punchy climbs balls to the wall, the blob pace in between meant we never went over cat limits. As soon as Inssbruck rolled along with its 20 min. climb, we were both over - along with 20 other peopleI agree with you, but because of the way the Cat system works I'd argue there's a 3rd reason for some riders who ride in a category below their true ability, and this is simply the nature of the Cat system and of most races and how they're raced.
The Cat system as we know is based on JUST 20 minute power and nothing else, but most races are decided on 1-5 minute power and/or a sprint, not 20 minute power. If you're racing sensibly, for the vast majority of races there's simply no need or reason to do high 20 minute power becuase you'll be sitting in a drafting pack and don't need to do a particularly hard 20 minute long effort. This isn't really sandbagging as such, it's just racing logically and sensibly, but it protects some riders from getting upgraded when they probably should.
Some people I'm sure go out of their way to game this part of the system too, but some who are capable of racing in a higher Cat still genuinely race as hard as they can, but simply don't exceed the Cat limits for these reasons.
That's why, if you want better categorisation (and you can't have results based systeme which most people would prefer) then you need to take more into account than 20 minute power alone. This Flamme Rouge event uses Normalised Power (NP) which is a great idea because it takes into account those high 1-2 minute power efforts which separate the top riders in a category from everyone else. E.G my 20 minute power in the last ZRL event was 273w (3.5w/kg) but NP was 324w (4.16w/kg). The Cat B winner of that race had NP of 4.53w/kg.

The difference in B is they hit the sprints and punchy climbs even harder bit the blob pace is actually pretty similar. Starts actually felt harder in C
