that's what it looks like but ....

The average delta for the last six weeks is 40, the spike is 10^6
greater.  I would have expect the 'averaging' functionality to ignore
the spike, maybe not immediately but eventutally.

While removing the spike from the rrd file is obviously possible, the 
development server has 2000 files, the live server nearly 10 times that.
It's not practical to reset every file everytime the database(s) are 
restarted.

It would appear that I'm stuck :-(((

Cheers
