Hottop KN-8828B-2K+ Roast Speed Slowing

I'm looking now at roast profiles from when I first got the machine, and it's taking a lot longer for the same roast now than it did new. I'm also seeing a much lower topping point. Seems like it's struggling to perform the same. Any ideas?

Its a year later, hopefully different beans, probably a diff ambient temperature and maybe diff humidity. The only thing that seems the same to me is the HotTop itself. It only takes a tiny change in these things to change the roast. I mean a tiny change. I have a B2k and do manual roasting. I will do 3-4 roasts each time I get the machine out. Clean the machine a bit between roasts but very well each time I put it away. Each roast is slightly different. Dunno ... residual heat probably; a thermal inertia. My strategy is simple and it works fairly well: 7 ounces, 270F bean drop, 4 mins to end of dry, 4 mins to 1st crack and 4 mins to bean eject. I have to adjust fan and heat the entire time but it all works out well as long as I buy beans in my taste profile.
