If you work on 1.4 as your max PPO2 then the calculation becomes
MOD = (14 / F02) - 10
and so on.
So plugging in 80% O2 on a 1.6 gives 10m.
As the turbaned one says though - 1.4 is considered safer for the working part of the dive.
That covers O2 CNS toxicity. There are a few ways to calculate oxygen pulmonary exposure as well, but you need tables or a PC for that.

You can be on my expedition team anyday. Thanks for adressing the question, not discussing my ignorance(maybe I should have known but I didn't which is why I asked), and getting sidetracked by petty details. A green spot for you, the only one who actually wrote out an equation. I'm quoting it in case someone missed it the first time. Please keep future dicussion on tis topic. If you would like to know why I don't know something, have a similiar experience or anything to share please do so with a private message and I will be happy to answer.
Thanks, Lazlo and others who focused on the question.
