need help doing a conversion for a 100m time

ok so i have been accidently running 110m on a grass track thinking it was 100m i went from 13.44 am now at 12.81… my question is what sort of times would i be getting in the 100m with these times? sub 12’s?

Maybe around 11.6 - 11.80. If thats hand timed, then add around 0.24 for FAT.

Hopefully faster on tartan

cool! thank you
