OPC Historic Tag , End Last ,Average Last

[Clearscada_EIT]

Hi,

I have my watchdog tag that is counting up by 1 every minute. 

I would like to retrieve the reading of this tag at 5 mins ago, and Average value of the past 5 minutes 

For retrieving value at 5 min ago, i used this expression : ".WatchDog;End Last;M;-5M"

For retrieving average value for last 5 mins, I used this expression : ".WatchDog;Average Last;M-5M;1M"

However, both values that calculated in Geoscada are incorrect.  (screenshot)

Can someone help

Thanks

@Clearscada_EIT The screenshot doesn't show the raw historic data over which the calculations are being performed so I can't see what the problem might be.
