Yeah, I suppose once we've identified an actual mechanism or two of abiogenesis, we'll be in a better position to estimate expected wait times in likely environments. And if the wait times are as fast as you suggest, it simply may not be possible to date rocks/minerals accurately enough for the necessary comparison.
