How large is the gap between Bane and Plagueis?

How large is the power gap between Bane and Plagueis?

Try to approximate and quantify

something along the lines of

start of POD bane <<< few years of training with the force < after getting confidence boost < after getting taught by githany <<< after he leaves and learns a lotta shit < after he fights and kills Kasim << him with 1 or 2 orbalisks << bane with like, 50 orbalisks ~ DOE bane <(<) Prime zannah < prime cognus < next master x26 < TPM sheev bost boost <(<) ROTS sheev << ROTJ sheev << DE sheev at the start < DE sheev at the end.

thats about it.
