In the newest UA that has been released on DnD beyond, Monks gain a new subclass called mystic arts. This is a problem present in both arcane trickster and Eldritch knight, which are current subclasses. They gain spell slots. If you check multiclassing information, they gain spell slots equal to one third of their level rounded down. This is inconsistent with the spell slots they actually gain without multiclassing. At 7th level they they gain their first second level spell slots, which typical spellcasters gain at 3rd level, which is inconsistent with the formula, where 7/3 is 2.33... rounded down is 2. This is the same with 13th and 19th level, where they gain 3rd level and 4th level spell slots respectively. 13/3 is 4.33... rounded down is 4, while normal spellcasters gain 3rd at 5th level. Likewise, 19/3 is 6.33... rounded down is 6. Normal spellcasters get it at 7. In addition half casters round up. The only thing that seems inconsistent that we round down when multiclassing with these, since everything shows the contrary. I believe we should fix this inconsistentcy.
The multiclass spell table is only used when multiclassing with another caster class, which is bringing at least one level to the table. So, even if you only have a single level of a half-caster, you're still getting your new spell levels at the same level you would if single-classed.
It's about spellcasting subclasses specifically. There seems to be a problem with them in their consistency, but I would agree with you half casters are pretty consistent. What I'm talking about is third casters. They get a third of spell slots, but it doesn't seem to be implemented in the same way if you take a multiclass rather than just one class.

It seems fine to me.

What's the circumstance where a multiclassed third-caster of level X is disadvantaged over a single classed third-caster of level X?
(X is their levels solely in fighter or thief, not their total levels.)
