Thanks for the chart. I just tried it on a new Kona (Rusty's Hawaiian)
and the end result looks very good. I have found the Konas to be very
"well behaved" beans that don't produce much chaff and always look and
taste great. I'll let you know if I can discern a difference between
this method and previous roasts. Again, thanks.

> 5-9 min 451 (so at 5 min, adjust dial to 451)
> 9-11 min 462 (again, at 9 min adjust to 462)
> 11- to first crack 482 (11 min, adjust to 482)
