As I understand MOA, it’s a bit over 1 inch at 100 yards.
So, it’ll be a bit over half inch at 50 yards
bit over quarter inch at 25 yards

So if your turret is a 1/4 MOA per click, 

To move 1/2 MOA (1/2 inch) at 100 yards is 2 clicks
to move 1/2 MOA (1/4 inch) at 50 yards is 2 clicks
to move 1/2 MOA (1/8 inch) at 25 yards is 2 clicks,

Or
to move 1/2 inch at 100 yards is 2 clicks
to move 1/2 inch at 50 yards is 4 clicks
to move 1/2 inch at 25 yards is 8 clicks

I don’t work well in equations, so this is easier for me to remember.  The number of clicks doubles each time you half the distance to the target, to move the scope zero the same distance across the target.
Feel free to fact check, as I’m self taught and that’s dangerous.
