In this case ranges 0:70 and 0:80 are assumed. State is OK if the value 
is inside both ranges (0-69), warning if value is outside warn and 
inside crit.

The area outside both ranges would be critical. But 65 would be critical 
either. There will be no ok state with these ranges. OK Zone is 60-70 if 
you define define -w 60:70 -c 60:80. 60-70 is inside both ranges here.

That's correct. But you might want to take care for the upper limit.
