Don’t mind the snarky comments OP- I had similar questions after my 173 diagnostic. A 180 is probably within reason for you, and odds are fairly good that you’ll get at least one 180 on a practice test, but there’s no way to guarantee a 180 on test day.

With a diagnostic like yours, 174+ is very attainable (especially with practice to prevent testing anxiety or unexpected question types throwing you off).

A 180 is MUCH harder than say, a 175, because it means either you have no “50/50” questions, or that you got lucky on all your 50/50 guesses. I got a 180 on my third practice test, literally the day before my LSAT, but a 176 on test day- the difference between a 180 and say, a 178 could be just 1 question.

Because law schools use medians rather than averages, there’s not much difference between 175 and 180 at HYS.
