Question about shock compression/rebound ratio

I have found conflicting information on my Comp. Engineering shock settings. My fronts are 3 way internally adjustable and rears are 12 way adjustable coilover.

One website says the first number (90/10) means extension and the second means compression. Also states on rear shocks it's the opposite.

Another site says on both it means extension/compression.

Another says it means compression/extension, which is what I thought it meant.

Is it different from front to rear, and what number is compression, what number is extension? I plan on drag racing so I want fast front end lift and no rear wheel spin or hop.

Thanks

90/10 drags shocks were designed to allow the front end to come up easier so only 10% of the shocks resistance was in effect on the extention and 90% of the resistance help hold the front end up for weight transfer on the compression Carlg

That's what I thought. The websites selling these shocks need to get their info straight.

Thanks
