Is it really coming or is it coming with what?

Currently, there is time loss since there is a downtime between rocket being ready and logistic robots bring time. By manually i can put them faster than robots so rocket goes up faster and also when "auto" selected insertion from chests by inserters are not possible. There is bigger loss if robots ...

If these coal generations are correct, then where are other resource generations? Because there are huge differences both in size and patch count between other resources with the same generation settings

Look at the both sizes and patch count of coal. They are very small and same for 4 values of percentages(50-17). Also why coal patches are "very much" higher than other resources despite same percentage?

When starting base radius is high and a resource's size/richness is high, low frequency values are either not considered or not calculated correctly. This actually happens more with stone and coal. Also "should not be there" resources size are also way lower than specified settings.
