you have to keep in mind that these percentages are just numbers. It's not like you're fine at 99% and you die when you reach 100%
I think many agencies advise that you have to calculate with toxicating above 75-80% of cns. On the other hand you could be fine with 200% as well.
It can be 150min at 1.4 bar to reach the 100% but at 1.6 bar its only 45 min. at 1.7 bar you have about 10 mins. At 1.8 bar it's like 4 mins or so. So you see the difference and how fast your time goes down if you have higher partial pressures.
if you have high ppo2 the chances are higher that you can get a instant cns toxification. In that case it's not important how high your cns percentage is. Under 1.6 bar it is considered to be stable.
