Eureka! 2 pounds of Mocha Kadir at 500 degrees. 1st crack at 11m30s, cut back to 480 - second crack at 14m - finish roast with a nice Full City + at 15m 30 sec. - no signs of divots. Thanks for the suggestions. It does baffle me though. It seems that everything I read on the subject suggested that somewhere in the process I was too hot and that was what caused the divots - some suggested too fast into 1st crack - others suggested too hot (therefore too fast) going from 1st to 2nd. Whatever it is, this seems like a nice profile.
Thanks again Shane.
