Consider this, if you have poor reliability overall, than qualifying results may represent overall driver+car performance better. So you can have one driver getting lion's share of poles, but if he can make it to the finish in only half of the time others will have a chance for the win.
So, if reliability plays significant role in driver's pole/win ratio, we should have fewer pole-sitters than winners.
Exactly. Apperently we were just saying the same. That's also why I need for every race every pole sitter and every race winner. Perhaps also other factors like sickness, crashes,... . Just to make sure not having too many omitted variable biases.
