Bug Description: Sneak calculations are either delivering incorrect information, or calculating detection incorrectly when moving diagonally. The moment the sneak effect is adjusted above 10%, diagonal regular moving becomes the same as unmitigated sneak sprinting.

Detailed steps to reproduce the bug:

1) Put yourself on a platform large enough to move/sprint sneak until the bar stabilizes. It is completely unobscured by walls or ceilings (this removes sun position as a factor and normalizes the numbers. It is also made of concrete cubes.)

2) Sneak-walk diagonally with zero armour on during the daytime on this elevated concrete platform (stabilizes at bouncing between 68-74 detection)

3) Put one point into from the shadows

4) Sneak-walk diagonally again (this will stabilize at between 74-78 now under the exact same conditions)

5) Level up to put another point into from the shadows (now level 2), and the same diagonal sneak walk stabilizes at 75-77

6) Level up to put another point to get to level 3 and it will not change.

7) Level up to 4 and there will still be no change

8 ) Finally, level to 5 in from the shadows. This is where we see no shift in the stabilized number, despite having 65% better sneak.

Actual result: The detection goes up after allocating the initial point, and does not scale down when allocating further points and sneak-walking diagonally.

Expected result: The detection should go down with each level, and walking diagonally should not be worse than sneak-sprinting diagonally.
