The list is essentially random in what's causing what, as it is.

What do you mean? Both lists appear to be sorted by microseconds per tick (us/t).

If you're looking at the ticks column, I have it that way so you can see if there are things running that are taking a high amount of tick time, but don't run every tick (useful for finding sources of burst lag). Check the 'Normalize results' button in the settings window and that will recompute every item's time per tick assuming it ran for every server tick that happened while profiling.

Is this issue still relevant, or can I close this?

I think I was looking at this part
