Yes, that is correct.

Because of the way it sounds. For LLE :
-If its running above fullspeed, it will sound faster then it should and it will have a crackling noise attached to it.
-If its running at fullspeed, it will sound normal.
-If its running below fullspeed, it wil stutter / skip. ( we all know this behaviour, and its completely different then when running above fullspeed, difference is easily recognisable ).

I dont think vps is beeing reported incorrectly because of DSP LLE speed and way it sounds.
There is no reason, and I dont think its even posible, for DSP LLE to run faster when VPS is at or below fullspeed.
Also, skid said that counter is not broken.
I am not sure what you mean with other part. 60 VPS will have exactly same effect with or without these settings, problem is when VPS is below 60, these settings get it back up to 60.

What behavior does each of the following produce?
1. Idle skipping off vbeam on
2. Idle skipping on vbeam on
3. Idle skipping off vbeam off

It is posible that these settings overide games throttling logic, this is emulator after all, stuff dont always work as they should Smile
Its very interesting question you asked, about what exactly each settings does, they are both capable of producing this effect on their own, but its usually best to combine them :
1. This is the setting which disables throtling always ( I dont want to use word synchronizing anymore because apperantly its incorrect usage of the word in this scenario ).
2. Enabling only vbeam usually doesnt disable VPS throttling on its own, but does sometimes in some games. For example, it doesnt do anything in SMG2 but provides slight speedup, FPS and VPS will still have same value.
3. Same can be said for only disabling idle skipping, doesnt do anything usually, but can sometimes. Strangest result is in SMG2, it seems to disable VPS throttling, but not in all parts of the game, and not as much as together with vbeam, in SMG2 I got 63 VPS instead of 111 at that exactly same place I already tested.

I already tried testing each settings seperately, and results vary very much and no clear consclusion can be made, except that these settings should be used together for best effect
