Are Thousandths of a Second Exposed by iRacing + Pit Countdown

Just ideas that occur to me while driving, not big deals, but I figured I'd ask anyway ...

I drive IndyCars in iRacing, and in this series, times are measured/reported in thousandths of a second, and gaps are < 1/100th more often than you might think. Especially in qualifying.

Does iRacing expose times in 1/1000ths and is it possible to report them with this precision, or are hundredths as specific as they send via the API?

Also:

The pit countdown is huge for me, because it's really easy for me to miss my crew and drive past them. By any chance, can we get a longer countdown?

Currently, for iRacing IndyCars, the time countdown does:

5 - 4 -3 -2 -1

and distance goes:

1,400 feet (or similar) -> 300 feet and I think 100 feet. At 55Mph pit road speed, that gives me about 3.7 seconds to come to a stop, so I tend to not use the outside pit lane for the runup because it's not enough notice to account for traffic that I might have to cut across.

Would it be possible to get updates every 100 feet, or maybe start the countdown from 10 or 20?

Or, as I suspect, is that the granularity that iRacing offers?
