I use the PREDICT function but i don't understand the operations made by
I have several questions:

-How does rrd set t0 and what is gap between NOW and t0?

-What is the comptutation made by rrd?
 Is it (for value at sample t0):

   Avg[ Avg(t0-shift1-window ; t0-shift1) ; Avg(t0-shift2-window;t0-shift2)

Is it the only operation made by rrd for getting  prediction?
