I think they are on to something - this part for me stood out (quote from Max Levchin)

  "Anything that can be measured, you record—and
  it’s applied to things like managing your weight,
  or deciding how likely you are to dope in the Tour
  de France. But with infertility? You get a Xerox
  from the 1960s.”

Most up-to-date fertility clinics use ultrasound and hormonal tracking to check the cycle; temperature & mucus are unreliable.

And, even if someone's ovulating or not-ovulating... it's often moot when it comes to whether to opt for fertility treatment. It's much more about time spent trying already, and finances.
