Anyway, the guy is 1.86m tall. Given a max FFMI of 25, we get,
Max lean mass = 25 x 1.86 x 1.86 = 86.5kg = 191lbs
His weight is given as 142kg (313lbs). So if he had lean mass 191lbs, then he would be (313-191)/313 = 39% bodyfat. I don't think so.

OK, so for me...
I'm about 203 cm tall so given a max FFMI of 25...
Max lean mas = 25 x 2.03 x 2.03 = 103 kg = 226 pounds
I weigh about 330 so then
(330 - 226)/330 = 31 % bodyfat... But I'm actually around 15% bodyfat.
Just like BMI, your FFMI isn't linear with height, and thus making absolute assumptions about 25 being the max you can obtain naturally is wrong and meaningless, IMHO.
