Burgertime Grouping Redux

Tonight I tried something new with my Burgertime pattern (original here).  If you watch the video you know that normally I'll walk up the ladder where the chef is standing in the image below, then walk to the right then press to the left and pepper the Mr. Hotdogs and Mr Egg in a vain attempt to group them.  They would always be grouped but the problem was that they were not grouped tight enough.  So, for the last couple days I've invested a few hours into Burgertime and have modified the pattern.  Instead of doing that "right then left" manuver and peppering the enemies as they come down the ladder I've instead walked to the right, gone up the ladder and when the chef's feet are aligned to the top rung (shown as the red dot below) I'd press down and pepper the enemies.  This has worked alot better, however...

I still choke on the latter stages...
