Any weight that you do that is more than what you did last week is a good weight.
As long as you're making personal records, you're doing great.
If you want to know what's good for competing in a meet, you can look up the records for the federation you want to compete in. Just remember that those are the records and aren't necessaraly what your competition will be doing at the meet you're going to.
Compete with yourself, unless you're looking to get trophies.
