yes, but that's relative to seat

Even I can't do less than 200 on reserve in the most senior category I can hold and I am a professional slacker that procrastinates. I could be page 1 in almost any FO seat and pull it off I'm sure but you still need 40%ish and skills to do it reliably. The top half of FOs are more savvy about RES than the top half of CAs for now but they will upgrade and take their knowledge with them. The current senior CAs are slowly learning but still have a general fear of RES. My biggest fear is that there is a mass learning event before they retire but fortunately they are mostly big money = big airplane thinkers.

REG averaging 48 block/month 13.5 days of work
RES averaging 12 block/month 4 days at work counting unused LC and SC as not at work

Reserve pays about the same with 5-6 SCC and some add pay (80ish)
