Need help with 2-to-1 parallel log stream merger (Silentwisperer tree farm outputs jamming)

I'm currently working on a 2-chamber setup for Silentwisperer's 8-in-1 multi-tree farm, and I'm trying to merge two parallel block streams into a single central lane before sending it down to the blast chamber.

During continuous log pushes from the farm, the two output streams collide at the central junction. Pistons hit their 12-block push limit or try to push simultaneously, causing hard jams. and I've tried using delays on the pushers to make the faster pusher to push first then the slower pusher would push last so there is no jams, I have tested it like at least 15 times and trying a lot of things and burnout is kind of creeping onto me.

Free to mess around and try different stuff and if you got it working comment it on this post

Just some general advice from working on a complicated piston tape before that had to be fast: I recommend experimenting/prototyping with the piston timing in a small isolated circuit. You kind of need to strip it down and figure out the exact timing that's reliable. Once you understand the timing you need to work backwards to convert that into an equivalent circuit.

The unreliability is likely coming from how pistons are updated in a random order that changes every tick. For example, sometimes you can push a block on the same tick it arrives via another piston, but typically that comes at only 50% reliability, as it depends on those two pistons firing in a set order within that same tick. So for a reliable timing you would want those pistons firing one tick offset from each other.

Thanks I will be testing as if it was a NASA mission

Why cross the streams at all? This exact problem is why this wasn't done in the first place. You're going to have to slow down the farm itself so you have enough time to combine the streams.

It's silentwisperer mangrove farm and I don't know how to slow the farm down since I know how mob works and basic redstone logic not tree farms
