To the best of my (non-expert) knowledge, the following is true:
The value 0.7 is an average (wait states are integers). However, most
motherboard manufacturers give you their 'best case' (zero) instead.
Some claim 'less than 1 wait state', though.

A typical value could easily be 0.7. I believe that memory reads tends
to 0.5 wait state on the average, while writes push the average up a bit.
