If you were in Arizona, perhaps, but not for New York. Full sun in New York doesn't have the sun as directly overhead as in places further south, but if you want to try shooting for 60 ppm then that might be a reasonable compromise. The thing is that it's a lot easier to add CYA than it is to lower it so if you are in a process of a partial drain/refill anyway, you might as well go lower to say 50 ppm since you can always easily add more CYA. Fresh water is also helpful pools generally since there are other things that accumulate besides CYA, though none of them are anywhere near as problematic as CYA. Up to you what to do -- just giving you the reasoning.
See this link (select "July" and "Horizontal Flat Plate") for a map of solar insolation on a horizontal surface to see that New York gets about 3/4ths the amount of sun as the southwestern U.S (June is even more extreme). Some of that is related to latitude since the sun is more directly overhead in the south but most of it is related to the very clear skies in the West compared to cloudier rainier summers in the Northeast.
