Seems to make a lot of big claims ("this might explain Dutch height!") based on an overall evidence of 'it worked for me and two other people I found on the internet, and for one friend, but not for the other' being called 'lightning doesn't strike twice' (which of course is a ridiculous claim itself).
Strictly, they said "lightning doesn't strike twice in the same place for different reasons", which is quite a bit more reasonable claim than the idiomatic and factually false "lightning doesn't strike twice in the same place", though whether it's actually an appropriate guideline is still a good question...
