Wolfgang: You're correct, I've obviously goofed this up, somehow!!! (sound of scurrying in yellowed soldering notes) Let me try and find the source for this to redeem myself.

my topside preheat is 97 deg. C and my peak temp. is 230 deg. C with a duration of 4 secs. What would be my Delta ? I suppose 230 minus 97 is equal to 133 deg C...is that right? regards
