I'd agree... I anneal at 968 and haven't had a problem with the Serena. Do you have multiple programs? Maybe you could set one for working with silver glass (I'm guessing that's why so low?) and one for the rest. Or set it to ramp down and hold at 925 after you're done working BE for the day? I do that when I work boro and soft in the same day... I start with boro, then ramp down to soft-glass holding temp.
For that matter, maybe the OP should try annealing a bit hotter and see if that solves her cracking problems?
