[TowerTalk] Yagi Optimizer file "Match" line

[Dan Maguire]

I have a K6STI YO (.yag) file that has this line:

Match: 2 0.3750 4.5000 54.0000 6.0000 0.0 50.0 0.0800

Can anyone interpret those parameters for me?  And a second question, does anyone have any documentation for YO files that explains this line?  Perhaps the user manual for the most recent (?) version of YO?

Dean Straw's "Yagi for Windows" manual does a good job of describing "YO like" file formats but doesn't mention a "Match" line.

Thanks.
