Who is the intended user for this? Pretty much anyone can calculate a mean and standard deviation without a bespoke website.

Yeah, what is a "professional grade" sharpe ratio compared to a shape ratio

I think professional-grade is referring to their calculator not the statistic. I don't see what would make this site better than throwing your CSV into a spreadsheet or a simple script that would make it considered professional-grade.

One of the benefits is that the risk free rate is kept up to date on a daily basis. The calculation matches for each day the actual risk free rate, rather than just using the latest available value.

I was wondering too. If someone is sophisticated enough to have their return data in a CSV, calculating a Sharpe ratio is trivial. The hard part is already done.
