Those sliders bothered me too. What's up with that? You can read them with approach circles but with HD it's like it appears out of nowhere.
Specifically:
02:39:707 (7) and then 02:40:350 (2). (2) just appears out of nowhere because it's exactly the same shape and spot and the time spacing from (7)'s fade (which happens when it's over) is only two white ticks.
There's also:
02:31:350 (1) and 02:31:993 (4) that kinda stack but this is fine(?) and doesn't need to be changed because (4)'s shape allows the end to be visible and you can sightread it (and thus deduce the start) even with HD, altho seeing the start circle's spot might be borderline.
