Why disc wheel for the sprinter?

Hi guys my first post.
i asking why a disc, and you hear, is more aero and is more stiff, ok but is more heavy too.
and as why know aero is more important in the front wheel but in the rear not much (and hear... but in pro level...) ok you have that small aero benefit, but sprinting is that, pure aceleration, and a more heavy wheel is slower for aceleration.

i make my test in the 250m track using 2 heavy covers for my training 30mm alloy rear wheel.
the test 500m TT standing start.
the result: 1s slower in the aero but heavy set. and you feel that extra watts needed for aceleration (after that aceleration point is more easy to mantain the speed for the rotational inertia, but i dont care im a sprinter )

i know a good disc is not too heavy but is more heavy than a good 60mm deep rim.
and a 60mm deep with 28 spokes is stiff ok.

so is not better a light option? FOR SPRINTING. NOT LONG DISTANCE NOT TRYA.

sorry for my english
