A simulation can be accurate, yet not be of anything that exists! I have literally done thousands of simulations of things that don't exist - and there wouldn't have been much point in any of them if they weren't accurate simulations.
Let's say I simulate a launcher in GGDT that doesn't exist, and get a velocity of 210 m/s. If that launcher would fire at 208 m/s if it was actually made in the real world, the simulation was accurate and
of something that didn't exist!
There is NOTHING that says a simulation of anything is automatically not accurate because what it simulates doesn't exist in the real world (be it yet, or ever).

Although it's not significant, it's more than you might expect.
At a range of perhaps 800 metres (at my own latitude), in a North to South shot, you could expect a .50 calibre bullet to deviate perhaps a centimetre due to the Coriolis effect alone.
Admittedly, not significant compared to other factors (such as wind), and unlikely to be enough to make you miss, but it does start to have an effect at ranges shorter than you might imagine.
