"Welded on spare tracks" armour in-game

[Taskforce]

As far as I know, the only nations using welded on spare tracks as an extra armour protection were Germany and the Western Allied nations. I haven't heard any example of the Soviet army doing this, at least not in any greater numbers - maybe the occational tank crew did this, but that would have been it.

I've read in a book about the fighting in East Preussia early 1945 that tests carried out after WW2 proved that welded on spare tracks provided protection against HE rounds but not so much against AP rounds, since the steel used to make the individual tracklinks wasn't as hardened as the steel used to make the tank armour.

So, in my mind that raises the question just how much extra armour protection a tank should get if spare tracks were welded on and what type of extra armour protection.

Should it be maybe 1 extra point of Steel armour or 1 extra point of HEAT armour?

What are your views on this issue?
