Discrepancy in Elevation Percentile Calculation Between User Manual and Source Code

[masseygeo]

There seems to be a discrepancy between the user manual and the source code for the ElevPercentile tool. The user manual describes the elevation percentile (EP) as being calculated based on the count of cells with higher elevation, but the source code correctly implements EP based on the count of cells with lower elevation (I think...I'm not a Rust expert). The discrepancy is also present in the code documentation header.

Existing description in user manual and tool documentation header:
EP = count_i∈C(z_i > z_0) * (100 / n_C)

Proposed Solution:
EP = count_i∈C(z_i < z_0) * (100 / n_C) or EP = count_i∈C(z_i <= z_0) * (100 / n_C)
The user manual & code documentation should be updated to reflect the correct calculation method, or a clarification should be added if the manual is describing a different metric (inverse elevation percentile?).
