Gathering % Rates

[Flarestar]

The percentages are simply a probability of success for each attempt. It is not for each node, or overall attempts. It is a very basic system, which reduces overhead by NOT looking at overall totals.

Example only: The game generates a number from 1-100 each time you attempt to gather something. It then compares this number to the actual probabilty. The higher number wins.

Probability=higher, you get the item
Probability=lower, you fail

The number is re-generated for each attempt, so there is no point in looking at large pools of data. This is obviously the system in use, just based on the inconsistent long-term results.

You need to go look at how RNG coding works. Over long term, properly coded RNG should in fact give predictable percentages, so yes, large pools of data absolutely do matter.
