Time-Weighted Average in Easy Chart

Just curious how the Time-Weighted Average option works in the easy chart pen setup screen and how it differs from Basic Average. I looked through the manual but it only has average and Min/Max in there. Thanks!

The Basic Average would return the average of two values. So, if you have two point, one being 2 and the other being 6, your basic average of the two would be 4.

The Time Weighted Average would work based on the values and the amount of time. Lets say you have a value of 2, and this value was recorded for 9 minutes. For the last minute, that value jumped to 6. The Time Weighted Average would return a value closer to 2 since that value was maintained the majority of the time.

Not the best explanation, hope it helps.
