00:00:153 (1,2,1,2) - should be the same idea to be honest. it should be a stop and start movement
00:00:153 (1,2) - being distanced from 00:00:575 (3,4) - is an intuitivly a good idea as 00:00:575 (3,4) - starts the guitar. but the execution visually is a bit unpleasant. that and I would probably change sv so it's a bit more apparent visually.
