Genie Scout 19 Doubt

Good evening

I find myself in an important existential doubt.

I have started using the Genie Scout editor for FM 19 and there is a big difference between Current ability and Potential ability VS Rating level and Rating potential level.

I do not understand why they vary in the results, when they should be the same, as well as to which of the 2 to pay attention to know the level or potential of the player.

I have also seen that there is an editor of the ratio coefficient within the menu to change the influence of the attributes and there are 3 versions 2015, 2018 and 2019.....

I don't know if there is someone expert or more experienced than me with the editor and can shed light on this darkness.

Thank you as always for all the help you can give me.

A greeting.

Think you need to ask the questions at fmscout?
