Yes, Doer made an observation on another thread a while back that if you put the biggest skill mod available, assume mod can increase your HA effectively beyond 10, and assume 80% hit for 0/10, 92% hit for 10/10 and continue the trend then you get remarkably close to 100% hit with the maximum skill mod.
However, I think at the time we decided it was probably coincidence as no-one has observed this actually happening.
