Trevor, the SharpCap bahtinov mask focus tool may provide the answer for you.
This tool converts the video footage of the standard bahtinov spikes into a rolling histogram on your screen. The aim is to get the histogram columns to zero for sharp focus. The display is large and very visual. I find it quick and accurate. You need the full SharpCap licence for this option to be active.
