measurement of attack and release on akai compressors

Hi
does anyone have any info on what measurements was used in akai comps( bus compressor-vca compressor-opto compressor- vintage compressor)
cause in compressors before you go to ear side you should be exactly where you want, like on swing when you know 66/67 is the perfect triple and 50 is totally perfect four so when your ear don't help you fully the knowledge comes to your hand
in attack and release there is just 0 to 100 and you just don't know what is 0 or 100.is it in s or ms
I did some experiments to find out at least about attack and it was like it is mostly fast attack like old compressors and it becomes kinda slow in 80 to 100 but I was totally wrong cause most of my mixes sound punchy and not thick
the akai comps are really cool sounding air is great too but there is something about akai comps itself that I really want to master I kinda think it could be cause they are RMS detector I don't know.there is no gain reduction and release and attack measurements are a mystery any info on the measurements would be great

Even with the Akai compressors set to the attack value of 100, the attack still sounds like it's in about 20 - 30 milliseconds.

yeah they seem so fast, but the weird thing is they still make the sound punch mostly so I just consider the measurements be like air comps measurement (in attack at least) which is correct but not specific. wish they would just show where is 10 ms or a gain reduction (just a number)
these comps are key reason that new mpcs are the greatest, you have all the mpc things and colors and you could turn your sound to ANYTHING if you know what you are doing, 70's fully recorded sounds electronic sounds 80's/90's hybrid sounds you could capture the essence of any sound any hardware or drum machine or more of that essence cause it's not automatic output you could suit it exactly to what you made.
how they made something this good sounding and then just put 0 to 100 as values just leaves me in wonder
