You can obtain 100.00% taming effectiveness on x1. Your feed timing and quality of honey (time until expiration) is key here. I just tamed a 150 at 100% for level 225 on x1 official. Use a fishing pole, equip honey, then unequip and the honey refreshes its expectation timer giving you a fresh honey and rinse & repeat. I continually refresh about 6-8 of my honey in between feedings.
For ps4 to throw honey put it in your last spot in your hot bar and press L1 L2 and control pad right arrow and you throw it right when it goes into its hole however if it burrows down without you throwing any honey the tameing will go down
