Hi everyone!
Catching up with the messages, I'll try to answer most of the questions raised, so:
1 - Is the multiplier applied before or after the vILV calculation? How is vILV calculated?
I noticed there's an incorrect perception on vILV calculation, that's my fault actually and it should be more clear in our documentations. So at the moment vILV is a smart contract that will return your balance based on your staked tokens and vesting tokens (for team/investors). The quadratic voting mechanism is a snapshot thing, so vILV contract performs calculations based on its code by querying Illuvium contracts, returns a raw vILV value which then snapshot applies the square root for the final voting power used in council elections. This means any weight multiplier is applied at the contract level, so the final result of someone that has for example 4.5 ILV staked for the max period would be:
**vILV contract return value: 4.5 ILV * 2 weight multiplier = 9 **
Snapshot voting power: sqrt(9) = 3
2 - Can we increase weight multiplier for those who are staked for longer?
Yes we can. Technically we could check when someone created a specific stake, and if lockedUntil > block.timestamp we use current block.timestamp value to calculate weight. And yes we could switch the equation to a logarithmic function for added weight post stake unlocking. However I'd need to test in terms of gas usage to make sure we're safely under eth_call read limit, i.e it's impossible for any staking address to be self DoS'ed, as checking stake lock period initial timestamp would require looping over each individual stake. So I'd say if that's something the community really wants to add in the proposal, give me a few days to test it before we make a call on it 
3 - Would vesting tokens receive a 1.0 weight multiplier or a 2.0 weight multiplier?
Technically we can move with any of these approaches. It's up to the community to the decide and that can be optionally included in the IIP or not, or voted separately as an ICCP later if preferred.
Hope that answers most questions 😄
