Hi Andrew,
Thanks for the tips ! :)
The last time we did one I thought it was right on 67F. Greengirl said no it reads 68F. I looked again and it looked like 67F to me. Greengirl said 68F. So I posted the test at 68F.
Getting it right on 67F was the hardest part of the test.
I am going to try your trick ! :)
Thanks, Steve
