Looks like mastertheknife made that change about 2 years ago:
https://github.com/ZoneMinder/ZoneMinde ... d6d39680c0

He is the one that wrote the performance patch, which significantly reduced the amount of cpu resources required by zoneminder. I'd leave it at 12 unless you have a reason not to.
Visit my blog for ZoneMinder related projects using the Raspberry Pi, Orange Pi, Odroid, and the ESP8266

Hi,

I'm actually not sure why i changed it, its been a long time.
Keep in mind that when fast blend is enabled (default), only these values are possible: 50%, 25%, 12.5%, 6.25%, 3.125% and 1.5%.
ZM rounds to the nearest one.

From my experience, 12.5% should be used for outdoors (because of clouds & weather changes) and 6.25% should be used indoors.
For outdoors you may also want to change "Alarm frame count" from 1 to 2 to reduce the amount of false alarms.
