I've noticed if I stretch a yellow inserter to drop 1 space out, and use the far side of the conveyor spot, it has this slide animation before it drops the item and this adds a little bit of time to the rotation. I can confirm it slows the throughput with the inserter throughput mod. It doesn't happen if I use the close side of the conveyor on the far drop point though. It's not a huge deal because I can work around it by moving it and changing it to a long grab instead of long drop, or just use the close side of the conveyor, but just wondering if this is supposed to be happening? The weird thing is it doesn't happen with mechanical (which are researched by default) or fast inserters.
