The current regression alert engine reports video_VideoDecodeMemoryUsage regression by the increase percentage from the previous measured value.
For example, the previous value is 10KB, and the current value is 50KB.
The alert engine reports since the increase percentage is 500%.
We would like to ignore in this case because the difference of the absolute value is small, 40KB.

There are two tasks for this.
(1) Change the engine to report a regression by comparing difference of absolute values.
(2) Determine a good threshold for each value.

Johny, could you investigate the way (1)?
Tomasz, may I please to do (2) if (1) is possible?

Thanks
