Cat Payload Scaling Technology on Motor Scrapers

Does anyone know how accurate or how user friendly Cat's Onboard Payload Scaling Technology is on Motor Scrapers?
Would the operator need to stay in place for 30 seconds to get an accurate settled weight? Or is it truly scaling on the go?
Interesting to know if a contractor can take those weights to the bank, and how the system works to gain an accurate payload if the load is shifted towards the front or back of the bowl?
Or is it actually inaccurate, and just a marketing ploy?
