High values of Gathering and Perception non-functional

[Nautix]

This is to do with itemization for Mining and Botany specifically.

Upon reaching 320 Perception, or 1% HQ on Out of Reach nodes, the Perception stat no longer has any effect.
Upon reaching 340 Gathering, or 90% success from Out of Reach nodes, Gathering no longer has any effect.

These 2 factors should be addressed or better communicated to players if not considered bugs.

Steps:
1. Raise Gathering to 335, success rate will be 89% on Out of Reach nodes.
2. Raise Gathering to 340, success rate will be 90% on Out of Reach nodes.
3. Raise Gathering above 345, success rate stays at 90% on Out of Reach nodes regardless of amount gained.

4. Get Perception to 320 to be able to HQ harvest from Out of Reach nodes.
5. Use food buffs and Materia to get above 320 (I tested to 345) and HQ % chance never increases.
