No, total drop will be affected beyond 40 but the drop per yard is going to be similar across arrow weights and speeds from 400-500gr.
Trajectory is a curve, you get to look at a small portion of that curve when looking through your sight. As you go heavier the portion of the curve you get to look at is shifted down but the section of the curve remains very stable.
407gr shaft going 300= 1.9” drop per yard at 50
475gr going 290 = 2.4” drop per yard at 50
515 going 270 = 2.6” drop per yard at 50.
Extreme spread of .7” inches when you have the pins or sight tape adjusted correctly for an apples to apples comparison.

I was researching this and came across this thread. Can you share how you calculated your drop numbers? Is there a basic formula you are using, or do you have some sort of software that's doing it? I have toyed with building a slightly lighter arrow (say going from 525gr down to 475gr), but I'm not convinced it's worth it if the trajectory impacts are this minimal.
