Dota 2 Shift Queue as a Clock Example

*I recommend watching this at 60 FPS so that the ring queue can be seen easier*
I use shift queue to count exactly 22 ticks to land a frame perfect eulstrike. This is basically an expansion of the frame perfect naga siren stun using basi/aquilla.
Play Invoker. Shift queue euls someone. Toggle shift queue on ring 22 times (22 ticks, 0.733 seconds) before the euls starts. Then shift queue sunstrike.
Tick 0: Euls Starts (2.5 second timer, 75 ticks), swap Basi
Tick 1-21: Swap Basi queue.
Tick 22: Activate Sunstrike: 1.7 second timer (51 ticks) + 0.05 second cast time rounds to 2 ticks; SS hits 53 ticks later
Tick 75: Euls Ends; Sunstrike Hits Frame Perfect.
Lina LSA, Lershrac, etc would work in a similar manner.
