Addition of new scaling comments

This patch is intended to prevent patches like 9b90cd8 and the subsequent reversion e3c9ed7 from happening again. Scaling behaviour of the reduction adjustments in the non-linear scaling section have been proven to >8 sigma:

STC: https://tests.stockfishchess.org/tests/view/6647b19f6dcff0d1d6b05d52
Elo: 4.28 ± 0.8 (95%) LOS: 100.0%
Total: 200000 W: 52555 L: 50094 D: 97351 Elo +4.28
Ptnml(0-2): 573, 22628, 51248, 24867, 684
nElo: 8.35 ± 1.5 (95%) PairsRatio: 1.10

VLTC: https://tests.stockfishchess.org/tests/view/6647b1b06dcff0d1d6b05d54
Elo: -1.48 ± 1.0 (95%) LOS: 0.2%
Total: 100000 W: 25009 L: 25436 D: 49555 Elo -1.48
Ptnml(0-2): 11, 10716, 28971, 10293, 9
nElo: -3.23 ± 2.2 (95%) PairsRatio: 0.96

The else if condition is moved to the non scaling section based on:
https://tests.stockfishchess.org/tests/view/664567a193ce6da3e93b3232 (It has no proven scaling)

General comment improvements and removal of a redundant margin condition have also been included.
