140 is the total network weight of all inputs online. You can check the weight (Coin*Day) of your inputs in the "Minting" tab. The input is ready to generate the block when the CoinDay is ≥ 1. For example, calculation for input with 0.03 coins: 1d / 0.03 + 42hrs = 33.3 + 1.75 ≈ 35 - after 35 days the input with 0.03 42 will be ready to generate the block. Ideal range is from 0.03 to 0.003, but if your input is larger the wallet will automatically split it when this input will find the block. Also you can set up the desirable split threshold in your 42.conf file by adding this line: splitthreshold=1000000 (value in dents) - means that the inputs smaller than 0.010 will not be splited.
You are such good developer why you are 'stack' with this coin?
I did not develop anything new and I am not a programmer, 42 is my first experience. I was a trader who does not sell at a loss but stuck with illiquid coin... And then "you become responsible forever, for what you have tamed" (Antoine de Saint-Exupery).
