Default General rules of thumb about timing?

Hello all. Can anyone 'splain the common timing ranges that are typically used? I am not trying to tune my own car, but I want to gain a little insight into the state of the tune I'm running.

How much advance is considered conservative, moderate, and aggressive for different load cases. Seems dyno plots typically show boost and AFR, but the timing variable is not disclosed.

No doubt things can vary widely depending on setup, so if that is the case let's consider a fairly typical stage 2 VF car on pump gas.

I am not asking for an explanation of what ignition advance is/does, just how much is used in different circumstances.

Thanks for the help.

For a stage 2 VF on pump, probably 12* at peak torque ramping up to around 20* at redline, all depending on how conservative/aggressive the fueling and boost is.
