Piston Rings?

All i know about Arias Pistons say that measurement have to be taken on the bottom of the Skirt.
Sure i have a smaller measurement 0.5" more up.

Bottom skirt 4.385
Middle is 4.383
at the Rings is 4.380

At the gauge point from CP its 4.384
Lets see what TS gives me on options...

When i want 0.004 - 0.005" clearance, i should bore to 4.390 or am i wrong?
Its not my first engine i build. but never had Pistons like these.
