> Source? I can't immediately find anything like that

I’ve financed two data centers. Most of my time was spent over permitting. If I tracked it minute by minute, it may be 70 to 95%. But broadly speaking, if I had to be told about it before it was solved, it was (a) a real nuisance and (b) not technical.

Unless you're the single largest cost, your personal time says nothing about actual DC costs, does it?

Just admit it was hyperbole.
