I have been paying attention. Matt has an SHO. He has done a lot of the performance trials and errors on his own personal SHO. I know the more he tinkers the more he figures out and uses that theory in his tunes. He flat out knows what he is doing.
This is complete speculation on my end. I think Matt knows what LMS knows in regard to Ford's "proprietary" software. LMS claims to be able to see things other tuners can't because they work exclusively with Ford. I think Matt now knows this too, and is better at tuning it. There are numerous posts on the other website where GH & AJPTurbo have publicly questioned LMS, and LMS' answers were not consistent nor held up to critical logic in regards to tuning.
