I've tried your tool on my league match.

As the tool said.. If I play down the middle my attack rate would be somewhere to.. 93%, If I use mixed would be 84%, and If I use down both flanks 72% or smth like this.

As a normal guy ofc that I started down the middle, mixed passes, offensive mentality, BAM! 0-0 at half time, I passed to down both flanks BAM! 3-0 full time, and I won the match haha.

Now I'm not saying that the tool is not good, but something is wrong with the tool or some factors influenced the game and that's why didn't match up those ''%'', I'll keep trying it to see more.
