you can see the "rule" how the wallet combine different inputs to solve a block  inside the wallet.cpp
the changes are client side and can be modified on your usage.

https://github.com/Tillkoeln/X2/blob/master/src/wallet.cpp#L19      means how much coins are  max combined until the wallet is able to stake
https://github.com/Tillkoeln/X2/blob/master/src/wallet.cpp#L1703  set the limit how much single inputs are used to solve a block.
max 100 inputs,   but never more then x


for some donations into my Gin+Hookers TipJar  i can build the client with the prefered settings for the user^^



+ info :
the Explorer is catching up and CMC should display all required infos on the next page update.
