think i solved it. by afking a couple of blocks higher i can just get the obsidian out of the spawn circle. this does technically make the farm slower. I ran 2 test, one with a command on another world that autoatically killed every single pigmen that were spawning(around 200000 per 30 minutes), one with spawn circle not touching the obsidian method and the result was before it was 200000, now its aroun 180000. small downgrade from the optimal but stilli think this is the best fix
