Lift angle communicates the parameters to the device so it knows what formula to translate the sounds from the microphone into metrics that understandable.
Lift angle is basically the distance of travel. If you drive for an hr and travel 60 miles your rate is 60mph but if the travel is 50 miles your rate is 50mph. You will want to feed the machine the correct distance.
Timing machines are basically an oscilloscope and there are parameters needed to read them accordingly. Beat rate and lift angle. Real time measurement isnt always accurate so professional devices allow us to measure over time for a true reading. Average over 1 min with 30 secs to stabilize for instance. This is measured in 5 positions.
You say ticks but like i said its tick tock tick. So imagine if 2 secs/d = tick + tock + tick
So for example.
Watch 1: tick-tock is 1.6 secs then tock-tick is adjusted to 0.4 secs to equal 2.0 secs
Watch 2: tick-tock is 1.4 secs then tock-tick is adjusted to 0.6 secs to equal 2.0 secs
Both would be +2 secs/d. Let assume tick-tock is amplitude. Then tock-tick would be adjustments that could be made to the balance wheel to compensate and adjust (regulate).
This isnt exactly how it works but it should at least break it down to some type of understandable language.
W/o visualizing the escapement its hard to explain and understand
