With the patch notes saying that a bug was fixed with plentiful harvest, although only the 10% star was mentioned.



I still wanted to test if perhaps this also fixed the persistent bug where max level on plentiful harvest was only giving ~40% doubled chance, rather than the 50% the tooltip states.

The test:

I collected 100 surveys on the PTS that I had stored on my PTS character copies from live. 10 of them were blacksmithing, 51 were woodworking, and 39 were clothing. Various zones. I collected in Vvardenfell, Bangkorai, Rivenspire, and Eastmarch.

The data:

600 total nodes were collected.

Of these, 297 of them were doubled.

This is a 49.5% doubling rate.

To check if this was statistically significant, I used a binomial distribution test in Google Sheets to check the percentile rank of getting that doubling rate, given a certain percentage.

At the old estimated 40% drop rate, it was at nearly 100% (99.9998964%), meaning we can virtually guarantee that the doubling rate is NOT 40%, as we were well above 4 standard deviations above the expected amount.

The conclusion:

The bug fix in plentiful harvest has definitively adjusted the drop rate when slotting plentiful harvest at the maximum value of 50%. It has most likely been "fixed" and is dropping at the expected rate of 50% now.
