Pet peeve of mine too - you'll never get close to that in summer here without a water chiller. I settled on 75F because I can (almost - occasionally ambient solutions will be 76-77 in the worst of summer heat) always use my Jobo to heat UP to that temperature.

Fortunately Ilford publishes a neat chart that makes equivalent conversion for starting points simple, then after the initial conversion I fine tune as usual except using 75F.
