Good point but if it is possible to get down to a more comfortable 75F
(which I used for the design param) then why not. Looks that with the
adjusted dry/wet bulb values I will be able to achieve it with a 5 tons
unit.

Seems like a 2-stage unit would take of this situation. Operating at a
low-speed during lower temp periods and kicking into high speed when temp
approaches the max design one.
