many thanks for the explanation.
so it should be fair to say that BIP 102 + SW would bring a gain between
2*1.6 and 2*2.
Just for the sake of simplicity if we take the middle of the interval we
could say
that BIP102 + SW will bring us a max block (virtual) size equal to 1MB * 2
* 1.8 = 3.6
Is it right?

isn't SegWit gain ~75%? hence 2mb x 1.75 = 3.5.
4x is theoric gain you get in case of 2-2 multisig txs.
am I missign something obvious?

this seems a fair explanation of what happened:
