Cool feature. I’d tend to agree the formula is a little too conservative. I’d rather look at when a game is a 95% or 99% lock, rather than a rock-solid 100% lock.
I’ve often thought that’d be a good way to measure how much one team dominated another for the purpose of computer rankings, rather than using point spread, since the point spread can be affected by when a coach pulls his starters, etc.

Now that you mention, it would be interesting to superimpose a graph of the “lead safeness” on top of the usual game flow chart. I’ll work on that.
