Phantasmal Sight Unknown Variables

?? appears to be the maximum amount of huge lucky bonuses that can be gathered via a single yellow ping, which increases to 2 at level 6.

I performed 4 test runs with a sample of 12 HS herb patches, and I'm fairly certain that var6 trough var9 refer to the chance of any individual color pinging. My results on average were: 10.24% Yellow, 41.84% Green, 23.61% Blue, 24.3% Purple

I could run further tests, but I have my doubts the result would change much. Unless someone else can confirm otherwise (either through testing or datamining) I think it's safe to assume that this is the case.

Edit: I performed tests an additional 6 times, and the results were consistent overall.
