Based on our 6+ years of experience and our user's feedback, we have set the following "Risk Levels" for each type of automated sending. The higher the risk, the more likely it is YouTube will have problems with what you're doing.
YouTube limits the number of actions that you can do every day so by setting lower send delays, it doesn't mean that you'll get more out per day. You can generally get just as many actions out per day in or Low Risk level as our High Risk level which is why we recommend you stick to the Low risk level.
One other note: If you send several days in a row, we suggest taking a day off and not sending for 24 hours before sending again.
