Why does no carbination chart include time?

I'm just not understanding kegging. I have just brewed my first ever batch of homebrew and I have a week and a half before I need to keg it and carbonate it.

The charts I'm seeing ALL are a function of PSI and TEMP. This doesn't make sense to me. Say I want 2.40 volumes of CO2 (a measurement I don't get!). According to the charts I need 16 PSI for my garage which maintains about 50º F. OK, great. I set the tank to 16 and connect it in my garage. BUT, how long does it take?! The darn charts don't say... Why can't I just use 32 PSI for HALF the time or some fraction thereof? Can I go up to 40 PSI or higher to get it done faster?

Ultimately I am expecting a 3D chart, or a calculation in a spreadsheet. Carbonation should be a factor of PSI, TEMP, and TIME, not just the first two.

Can anyone explain what I'm not getting here?

Here you go: chart

Eventually you will learn by doing. Every beer is different so I don't think you could realistically produce a chart showing time, other than approximate. Many keggers do something like 30psi for 24-36 hours and then set to serving pressure and let it sit for a week+. Some just set it to serving pressure and wait 10-14 or so. I favor the 24 hours@ 30 psi then set to serving pressure and start testing it after 5 days or so. Really don't start to drink it a lot until 10 days or more.

When you get it all figured out, I think everyone would be blown away by a chart with all the factors included.
