I like this approach and have started using it myself as I’ve expanded beyond ID’s in my province. I also wonder if we tie ourselves to the goal of completion (or at least near completion) and that chasing this unrealistic goal is a source of burnout/discouragement for IDers. I’d love nothing more than to review all the species X from area Y, but unless those categories are very restrictive, that’s never going to happen.
This is not to say that new IDers aren’t welcome (please come!), but perhaps our goal being completion is something we (including me) need to hold a bit more loosely.
