Hi Alex, yes you're right, but in this case, 1,0,0,unknown will result in 33% as the calculation is made like:
count all values > -1 add all values divide counted/added CDEF:ResponseSum=PREV,UN,0,PREV,IF,Cleaned,+ CDEF:One=Cleaned,-1,GT CDEF:OneSum=PREV,UN,0,PREV,IF,One,+ CDEF:Uptime=ResponseSum,OneSum,/ which means, when counting, nans are ignored, when adding nans are ignored so you'll find 1/3. But I hope that this is exactly what Eric wants to achieve.
