If they were out to screw Everton over, there'd be no value in the commission saying they didn't use the formula, then actively using the formula. They'd just use the formula. Sorry mate, it's a moronic argument.
They could be out to screw Everton over if:
they used the formula and said so
didn't use the formula and said so
used the formula and didn't say so
didn't use the formula and didn't say so
They could also
not be out to screw Everton over and any one of the above be true, as it is unrelated to intent and a meaningless connection
telling someone they are making a moronic argument when your own makes no sense is a bit rich
