It's our pleasure. For the group stake, it will be nice to have coins controlled in an amount of "middle" value because of the PoS-II design. Though it's a good idea, I am a little bit worry about staking by exchange or cloud staking pools. Exchanges could be advantageous in this regard once coins automatically gets consolidated. The PoS-II enables a staking window for best results; with many small transactions will come less advantageous as like staking huge amount coins in a transaction. In other words, people can be diligent to stake "effectively", while some parties won't be able to do so; that seems not a bad news.
And yeah, we get chance to spread the PoS-II (like NOBL) and I welcome anyone else who is interested to this idea. That turns out it seems going nice so far.
group stake is in wallet code each DMD wallet utilize group stake
coin age between min and max age try to split stake (=if successful minted coin pile is split in 2 parts same as all ur XMG POS blocks)
coin age above max age try to group stake (=a coin pile above max age check if he is below 100 dmd if yes he seek if another coin pile above max age and below 100 dmd is in wallet and repeat that until all together are over 100 dmd and then this group stake together and if successful minting a block they merge together and become one coin pile)
the reason this not work in most pos coins is because they copy code and dont analyze it in detail and adapt values
in ur case without check ur code if u keep the important code parts for group stake unchanged then the value which is set at 100 at dmd is for u linked to POW reward and 1/3 of it (if u did keep that original code lines)
the orgin of group stake comes from original PPC code and there the group value is linked to pow block reward value
and in code not explained and a note with do not touch (which 99% of devs did and by this achieved to have group stake inactive)
planing to have a nice amount of XMG i hope u get group stake in so i can let the wallets run 24/7 without fear coin piles split stake into dust size
