Overiding IBTS Preheat to get BT probe up to Drop temp

Roasting on the Bullet
1

Hey folks. I am experiencing a situation with my roasting conditions. TL;DR is this - I need my BT Probe Drop temp to be 200C - but IBTS at 310C (max) wont get it that high from cool - Should I blind roast for a minute or so for the heat to get high enough and then go through Preheat again??? (I use BT for my batch size, im a probat user when i was working in a larger roastery - IBTS is great, but not my main marker)

Explanation - I preheat my roaster to 300/310C on the IBTS (Max setting) which yeilds a 185/190C drop temp (from cold). however, after 2 roasts, always get my BT probe to 200C without fail (Solid Heat in the drum and surroundings)

My recipe for a Brazil requires 200C drop temp so it doesnt legnthen the Maillard and overall roast (cool start with high energy P9 - adds an extra 45 to 1 minutes)

How many minutes do you preheat the first time? If you preheat for about 20+ Minutes to begin with (even if you get the Charge Prompt in between), the BT usually does go up to 200C and beyond. In fact in my case, it is the second back-to-back roast that does not have as much momentum as the first roast.

I usually just aloow it to go to the charge prompt. I dont think I have let the roaster sit idle when the Charge Prompt takes place, but looking at the way it still fluctuates between power settings to float the temperature, and by what you have said, I assume I can just let it idle until I reach my temperature?
