HQ Gathering StatisticsFollow

So I have been doing a bunch of gathering lately trying to grind it out until I can harvest Flax for Weaving. We all know that you get better rewards for giving up HQ GC daily supplies than with NQ. Also, most of the class quests involve harvesting HQ items as well.

I decided to take a look at the statistics as to how to best use my CP to get the best HQ Gathering Rate. I just did some quick calculations using Microsoft Excel and don't really know how to format it well here, if anyone knows how to clean it up <please> <help me out!>. I was trying to put the data side by side for better comparison.

This assumes that
Overall HQ Gathering Rate = Gathering Rate% x HQ Chance%

Examining two skills to start: Field Mastery (50CP cost for +5% Gathering Rate) and Leaf Turn (100CP for 10% HQ Chance) with a base HQ Chance of 12.

The table on the left is for Field Mastery and on the right compares Leaf Turn. The columns in order are Base Gathering Rate, HQ Chance, Overall HQ Gathering Rate. All units are %s

 
BGR	HQC	OHQR	BGR	HQC	OHQR	Factored for CP Cost 
60	12	7.2	60	22	13.2	6.6 
65	12	7.8	65	22	14.3	7.15 
70	12	8.4	70	22	15.4	7.7 
75	12	9	75	22	16.5	8.25 
80	12	9.6	80	22	17.6	8.8 
85	12	10.2	85	22	18.7	9.35 
90	12	10.8	90	22	19.8	9.9 
95	12	11.4	95	22	20.9	10.45 
100	12	12	100	22	22	11 

Looking at this data it seems to show that using Field Mastery will always give an overall better HQ Gathering Rate due to the fact that Leaf Turn costs twice as much GP to use and therefore can only really be used half as often.

Also interesting to note that this still holds true even when harvesting from a tree with the 5% fortune bonus. See table below:

 
BGR	HQC	OHQR	BGR	HQC	OHQR	Factored for CP Cost 
60	17	10.2	60	27	16.2	8.1 
65	17	11.05	65	27	17.55	8.775 
70	17	11.9	70	27	18.9	9.45 
75	17	12.75	75	27	20.25	10.125 
80	17	13.6	80	27	21.6	10.8 
85	17	14.45	85	27	22.95	11.475 
90	17	15.3	90	27	24.3	12.15 
95	17	16.15	95	27	25.65	12.825 
100	17	17	100	27	27	13.5 

If the math is incorrect I’d be open to discussion. What do you guys think?

Thanks for taking interest. I knew I couldn't be the only mathematically inclined gatherer out there

So far it seems useless to actually use Leaf Turn if you are going for the best overall HQ rate over time.

I find that neither skill is wholly effective at providing a noticeable results given the small scope of typical gathering and a wildly streaky (some would say churlish) RNG. I don't believe you can simply halve the resulting gathering rate like you did, you have to do quite a bit more math including: Harvesting duration, GP cap, GP regeneration (100GP/min), speed of gathering (travel time between nodes included), and factoring the relative value of the Whisper skills (is 5% gather relatively useful if my base rate of gather is 95%?).

The problem I find is that the math doesn't balance, if you go from a typical 85% to 90% gather rate you will still blow streaks of gathers. I typically will use the +10% gather skill for MIN/BTN when the conditions are right and almost never use rank one mastery as the value has not proven itself over many uses.
