no you don't do anything wrong, unless the pool you use let you set up the difficulty of the share you are hashing and you don't.
But some pool, tends to assume we all have big farm and when you use a small miner it might still get somewhat too high difficulty share:
which mean you will send less work than larger miner, getting a hashrate report also smaller (because the pool doesn't get enough share to make a proper discussion). My advice would be to stay away from those pool as you will get ripped off...
But make sure that it isn't possible to tell the pool which difficulty shares you want to solve (through a parameter).
This might be in the help section of the pool if it exists
ps: never heard of any of the coin you are mining
