According to the figures currently on that website, 73 patients were admitted with COVID-19, apparently 85.1% of whom are unvaccinated.

85.1% of 73 is 62.123. This implies 62 (or possibly 63) of those 73 patients were unvaccinated, and 62 out of 73 is 84.9% (and 63 out of 73 is 86.3%).
So how do they get 85.1%?
Is the 73 just the number admitted in the past 24 hours, whereas the 85.1% includes patients previously admitted?
I simply report, I do not analyze the report. Contact the hospital for your questions.
