Calculating the longest duration over which a value was maintained in an Excel column

[zacuk]

Hi, In my Excel file, column 'V' has data from a process and the value peaks to around 6.0 at multiple times, during the process. The time corresponding to each data point is captured in a separate column 'C'. I would consider all values between 5.5 and 6.0 as the peak. Some time the peak value is maintained for 2 hours before dropping down to <5.5. At other times, it can be up for 6 hours.


I am interested in finding out the 'Maximum duration' over which the peak value (5.5-6.0) was maintained.


I am not much used to VBA, so a formula would be great. Otherwise, I'd appreciate if you can write the VBA code which I paste in the macro box and run it, please.


Thanks

PS: Forgot to mention that I have managed to write a formula but it works with the highest number only. So, e.g., it would give the duration for which the value stayed it 6.0 and ignores the peak at 5.9 even if it lasted for longer than when the value was 6.0.

The formula I have made is based on Index/match using offset function to set the lookup range start at the max value.

I want the formula to return the output based on the max duration whether it is for the peak at 6.0 or 5.9. Thanks
