Returning to our discussion;))))))) I’ve understood that:
Archbishop costs 8 because it also covers neighboring squares (earlier I thought of it as of BFX discarding the nearness of covered squares); in my opinion it's because B part is long ranging (discarding N's moving's shortness) and N part is color-switching (discarding B's colorboundness) and jumping; so it is maneuverable. So Bishop's part there is 4, however Knight's one is also 4!
Imbalance of A+p > Q probably exists because Pawn is cooperative and "every pawn is potential Queen"(c)
Ultrabishop (BW) and Hyperrook (RF) are 7 and 8 relatively, because they BTW include the Doubler (K) moves (I thought of them like about BH or RA/RG discarding the nearness of covered squares).
Nightrider and Rook really have similar mobility on 8x8, but Nightrider is more maneuverable and Rook is more reliable.
Both Zip and Magician from Horizons have the cost of 9 on large (but not big) and free boards, but on 8x8 they really are 7 (M) and 8 (Z) because of their maneuverability and defense from the King (compare with Queen).
Bishop pair costs between 6,5 and 7 (when board is more free, Bishops' pair is more valuable).
Silver isn't as stabile in cost as I've thought before (in Orda Chess, it's Yurt which is decided to cost 2, but I disagree – maybe from 2,6 to 3,2).

What do you think about?
