League hopping.

I am just wondering about this.....

It was bought to my attention about some managers hopping from 1 league to another to change their % from 1 season to the next..

I know that if you have a high % and join a league with lower % you will lose some when you join, but does this work the other way around?

If your on 10% and join a leage with others on an average of 80% will you gain?

I have only ever been in 2 leagues since I started, So I have no idea if it is true or not..

Any feedback about this or any clues to league hopping advantages will be appreciated.

Thanks

JFYI: I know when I signed up I league hop 15 times but I was looking at info I couldnt seem to find before joinning...I wasnt doing to use an exploit. I forget at the moment why I had too but umm Yeah I hop in and out after find the required info.

But that doesn't stop you having 100% and to get a better chance of gaining %  is to leave a league before the end.. Get it dropped and then re-join the same league you left with lower dev % so it doesn't stop you for testing for the next???


Maybe a week lock down from leaving a league and re-joining the same one will stop this???
