In a semi-scientific test I tried to dial in the best delay for message sending and for friend requests, and in both cases I found that the most efficient technique (for getting in the highest number of messages/requests before triggering the YouTube-imposed limits) seemed to be a "burst" of requests/messages with a 10 minute "cool-down" to reset the YouTube limit, then to repeat that cycle as long as desired.

So what I would request is this - some way to set a "delay" in between "bursts" - a second timer that allows for a pre-determined "cooldown" inbetween request/message cycles.

Ideally I would like to be able to send 9 friend requests at 30-90 seconds between each - then a delay of 10 minutes - then another "burst" of 9 requests, and so on, until 200 or so requests are send out.

With messages the best technique seems to be 3 messages, then a 10 minute delay, then another 3 messages and repeat...

...so, long story long, is there some way to built in a second duration in between bursts?

Does that make sense...?
