Carol, very sorry to hear of your slump. I don't know about providing a pep talk, not my forte. I would point out the obvious; you are one of the top stall-catchers of all time, and even the best, in baseball, tennis or golf for example, have rough spells now & then. You'll be back - no question. Meanwhile, you're still making a valued contribution.
I could commiserate a bit, however. I've been missing more calibrations of late than usual myself. Maybe they snuck in a few new ones on us? There's one in particular I keep 'missing' consistently. I know it's going to pop up now & then, but when it does, I can't quite yet bring myself to provide the "correct" response. (Well, sometimes I just forget - 'Oh, it's that one!') I do rather enjoy clawing my way back up the skill bar, however, so aside from the embarrassment, I don't mind the occasional miss. It breaks up the tedium, especially while we're awaiting some fresh meat to evaluate.
So, sharpen your claws, hang in there, Carol, & I'll look forward to 'seeing' you again this evening.
