My point is: if Mayer had been aware that 1s over 400m was worth more than 1m in the shot put, then he would have trained in order to achieve 47"50 over 400rather than 16,50 in the shot put.
Decathlon is not about "is 19,36 worth more than 45,00?", it's about maximizing your point total over ten events knowing the associated scoring table.

It's interesting to note than KM point difference between his PB and the sum of his 10 individual PBs is 298, lowest of the top 10 list.
There is no doubt Dan O'Brien and Ashton Eaton are better athletes. But Mayer is the best decathlete whatever the scoring table says.
