Could someone elaborate more on what "Proven weighting with some tweaks" means? Does it mean each algorithm has a variable weight to find a block or is it related to the block reward?
Is it possible to dynamically change the block reward to be based on the size of the network hashrate of that algorithm relative to the rest of the network? This would perhaps encourage a more fair distribution of hashing power across the algorithms.
"Proven weighting with some tweaks"? I'll take a stab. Without getting too technical, I think what that means is that each algo is automatically weighted by its own individual difficulty derived from a shared ratio: SHA-256 could have a network hashrate that is sky high that would cause its individual diff to also be sky high, meaning that its proportionate payout weighting would be much less than the same MH/s Qubit payout with a low network hashrate and low diff. As for the "tweaking" part of that statement, we can only hope for what we'd each like to see, and then patiently wait and see.

DigiShield dynamically changes the block reward on a per MH/s percentage basis - the total isn't changed, but the difficulty is changed such that it still takes the same time to solve then next block (on average) regardless of how much hashrate you throw at it, meaning that the per MH/s split is automatically lowered. All coins incorporate a diff algorithm of some sort. Other examples of dynamic block rewards would be DOGE, for example, that originally had a random block reward, and the most recent and creative that I've seen, AID, whose block reward actually increases on a rough 8:1 ratio to diff!
