Re: [Roll] trickle question

Hello Phil and Julien,

Is it really necessary to wait until the complete I interval has
passed before doubling I and restarting T (with the new interval)?

It feels that we get basically the same behavior with less complex
code if we skip the wait for the complete interval to pass.


Best regards,
