Microphone placement phase issue

I also posted this at Logic Pro help but i like to hear the ideas here. I also posted this dilemma once but I thought it might make more senesce if I were to present it in a different light. The game here is not to manually nudge and edit each track over and over. the recorded audio is difficult to identify rather then this clean and easy to read since wave. Tried to find a way to build a compensation setting for each region into my template so the recorded regions are corrected. I zoomed in to show the delay for each microphone which is placed slightly further away. Sometimes only two or three are used but the mixture is tainted with phase issues. I have tried zooming in and using option arrow left & right but the region jumps far to much either direction. Like I said, I am trying to come up with an accurate way to create the corrections and leave them set in a template. I leave the microphones in the same place for recording so they do not move. Screen shot of regions with a test signal recorded and recording booth included. Should I retard the earliest mic to the latest and so on, or advance the latest mic to the earliest? Phase correction usually calls for adjustment of the closer of the two mics against the farthest but this is 5 microphone set up and I would like to create a correction that makes sense. I saw Pro tools had a plug in that made the measurement and allowed the offset in samples to be corrected for two microphones set about one 18 inches apart. They were also different types but the distance is the key, Phase of the Microphones is good from one mic to the next. It's simply a time delay from placement.
