they aren't quite results, a hypothesis - maybe, still need more info (see above) - I've figured out '70 St. Louis & most of Line #1 at Hamtramck, Lynch Rd. would need 100s of hours put into it to get "0A" better than the above "smaller than a ballpark-snapshot of 929" but it is getting close - then there's the other plants/other years ..... I'm using anything I can get my hands/eyes on
