On question, I covered that here:
Even a basic source that gives an idea of what shells spesifcally it was supposed to provide protection against (not just generically saying KE as that's extremely open ended) would help provide a better picture of what sort of estimated protection it may have. Other tanks have had sources like this taken into consideration for their armour. A direct value is often not possible, but having no framework at all to base it on unfortunately means nothing can be changed in the meantime.
On the second point, I'm aware that it's generally (in most cases) not directed at me. I and anyone else providing responses can appreciate frustration that a particular vehcile might not be the way you particularly want to see it. All I can do however is relay the facts as they are from the developers and provide the responses in what can and can't be accepted.
