best argument for l3+

hello guys i have been using my antminer l3+ since 2 weeks and ive seen that the payouts is lower each day can someone tell me the best static difficulty for my miner to make 25-30 dollars because i am making 20 dollars maximum thank you.

The pool does have a smart ability to point a specific miner to specific coins. So the pool should know that a l3+ do need a minimum amount of difficluty in order to run efficient. You can also play with this by yourself, the sweetspot for l3+ is around 131k. Try set it a few times higher or lower then this and see what happens. The payout Always get lower and lower as long as new miners enter to maintain the ledger.
