if it were an eight speed cassette, I'd paint a different picture with my thoughts.
9+ cassette with 11 speed crank, i expect that it'll be ok. I haven't put raw numbers together to establish a professional data sheet, but even then a real world test can reveal different outcomes that calculated data might not factor.
