Question about the way rakeback is calculated

[SEABEAST]

I have 2 questions about the way rakeback is calculated.

1) Is the amount of rake I am considered to have paid all of the rake taken from the pots I drag, or is it my share of all rake paid to the casino from tables I am active at? If I lose a pot am I considered to have contributed to the rake from that pot? If I fold preflop am I considered to have contributed?

2) Hypothetically, is the amount of rake my pokertracker shows me to have paid a reliable method of determining how much rakeback I should be due to receive? Or is it determined in a different manner to rakeback revenue?

If anyone can clear this up for me and help me better understand the way this stuff works that would be much appreciated, thanks...
