Vehicle Size- Does size matter?

[Pibwl]

I don't feel that sizes need general changing, but only my 3 cents: most important IMO should be height and "fullness" of silhouette (say, boxlike APC should be bigger target, than a tank with low hull and only streamlined turret reaching the same height, as APC's roof). Barrel is IMO negligible.

Tanks similar to T-54 are size 4, tanks similar to M-48/Centurion/Leo-II are size 5 and it seems OK. There will be always problems with border cases, and it's subjective. Mathematical formula won't help much, because a difference of 10 cm might decide, if it's 4 or 5. (I've had a similar problem long ago, when I was modifying aircraft sizes in SP-I).

Having said this, I think, that PT-76 is too small (3), comparing to T-54.
