Hi, reopening this issue

thanks

boschmonart commented 8 months ago

Difference seems to come from the limit in channel constrains (200%). Would make sense to increase this to for example 1k%? or this 10x increase are outside of robyn scope?

Sorry for the late reply. Please see the schema here

in general, it's risky to 10x the spend constraints. It's not very realistic to expect this kind of "prediction" to be very accurate.
