So heres my take.
Clearly they are using smaller BG at this time. The last few busy weeks were probably “stress tests” to see how much punishment the ride could handle before something over heated or broke.
They are now dialing it back, and will give out less BG and More Back ups. Proably constrained from loading times versus peak efficiency, versus malfunctions. They are still trying to find the sweet spot.
I really do not think getting up at 4am is warrented at this point. As long as you are at the styles 30-45 minutes before opening you will be in the park and have the same chances as everyone else to snag a group. Getting that early group is totally random due to all the factors involved.
As for StarBucks, I hate that place on principal. So I will find somewhere else for my nibbles or get them before park opens
