As most of you know, when your opponent is at low health (24 or lower), they take half damage if the attack does 20 damage or less (base damage). This also applies during combos. A lot of Yoshi's combo enders involve a bunch of light attacks, like 6B+KBBB and 2(A+B)6(6). Even though the difference can be very small (usually only 4-6 damage) you generally want to avoid those enders and do the alternative enders, even they usually do less damage. 2A+B66 is an especially bad ender after Deathcopter hits a standing opponent, even 3B is better. CE is mostly unaffected, since the last two hits do 21 damage.
To test this in training mode you have to get the training dummy's health bar low without resetting, which done by having some attack or stance active at all times. For example, do 3B 6K, buffer B+K, hit G and buffer 3B 6K, buffer B+K, hit G, etc, walking forward in FLE if you have to.
