Hey Tom,
Yes it can be quite tricky to actually know the level of different leagues. There is no real clear black or white answer to this unfortunately, usually its a case of just having a look and trying to see where you feel your level best fits into what league. If there are other players who play and also know your level they will give you an idea of which league to try and aim for too.
I would say ask some players at your club and try to get as much information about the standard in each division and where you would best fit it. It’s always a tricky one as each area is different in terms of strength. It’s easier when it comes to national and international level as there are rankings etc to go by but not easy when your first starting out in league play!
