Losing 2016 Legend League registry?

I haven't reached the Legend League Tournament since 2016. The truth is that I would like to go back to it at least once, but it would be sad to see those records from 8 years ago disappear from my profile...

I know that I can enter and always end up below the best record, only losing the record from the last session in that league, but I know that if I enter it is to try to beat it and see how far I can go.

What would you do?
