Start xx:xx:

Tracker speed test: 2MHz internal Trigger from TLU -> works.

Start xx:xx:

Tracker speed test: 4MHz internal Trigger from TLU -> works.
Tracker Setting: max_trigger=1 and trigger_busy=25. This gives ~20kHz eventrate.

Start 22:23 (Run79), 22:30, 22:37, 22:43 

Synchronization: Playing around with trgger_busy (range 25-500) This slows down Eventrate, but does not solve our issue of not being able to count all overflows. (This depends on the ratio of events hitting the MPW2 only, NOT on the overall busy rate)
