Please clarify for me.  Hummm...my bins are 10 minutes wide on the 10 minutes.

If I bin a value 1000 at 10:35, the value displayed on that graph is 1000 for the 10 minute bin...correct?
Now suppose I add another value (2000) at 10:37. What will be the value for that 10 minute bin? 3000?

I am sure that there is something simple I am missing here.

RRDtool calculates the value at ,say, 10:60 based on the values it got at 10:50, 10:59 and 10:70.
