Charlie there is not other owner in the spreadsheet for the battor benchmarks (https://docs.google.com/spreadsheets/d/1R_1BAOd3xeVtR0jn6wB5HHJ2K25mIbKp3iIRQKkX38o/edit#gid=0), could you assign to the appropriate person to investigate?

A few different tests seem to be failing with the same stack trace on Win 10 High-DPI Perf (1) and (5)
