I use the Curve Viewer window (under the Tools tab) and overlay the Uncorrected Response, Corrected Response, Target Line, and EQ Line. As you change the Max EQ setting, I look at where the EQ Line values change.
Let's say you have a correctable dip at 85Hz and a dip at 4kHz for your surrounds (along with various other corrections in-between). The odds are ARC will roll your speaker off higher than 85Hz so it doesn't have to correct that dip, freeing up a correction filter that could be used on the 4kHz dip (assuming there was only one correction filter left to use in this example).
Changing your Max EQ to 3.5kHz in this instance would than free up that correction filter applied at 4kHz to possibly be used at the 85Hz dip, allowing you to have a lower crossover point.
Very simplistic explanation, but it hopefully gets the jist of it across. ARC only has so many correction filters available and it will "prioritize" spikes/dips based on the Max EQ setting. Same with the Subwoofer EQ setting. Mine was at 200Hz, but lowering it to 160Hz freed up a correction point to bump up my low end, allowing for a flat response down to 20Hz.
In fact, the exact changes I made for my subwoofer is what Anthem recommended when I emailed them my file. So I feel a little proud lol
As far as what the "optimal" setting should look like: compare the corrected line to the target line as you change the Max EQ setting. Does it get flatter? Does it allow you to have a lower crossover point while still being flat? It's a lot of compare/contrasting of the EQ graphs as you change the setting.
But that is also why I recommend using the Curve Viewer screen to see the various lines together, because ARC will not apply more then a +/-6dB of correction to a filter. So you may have a dip at the low end you want to bring up by changing the Max EQ but find it isn't making a difference...most likely because the max of 6dB has already been applied to that dip (shown by looking at the EQ line in Curve Viewer).
