Changed some worms to 100% and also 1 python salt/lead to salt/merc
and here's result
The purity of bins is hard-capping humus(even with best worms it will never go over 0%)
i could make some more test with diffrent sets of worms(low purity, high purity, diffrent amount) just say if there is any special combination you are interested in(only worms/only pythons etc.)
