Driving readings indoors no problem

What is Your setting in range between unit and hitting area?

Minimum? 

I'm also interested in your setup when the R10 is 4 feet behind the ball.  1) What did you set the "Distance from R10" setting (6' - 8') to ?  2) What is the distance from the ball to your net or screen? 3) What weather condition settings do you use ?

Usually 7.5 ft behind ball 

distance to screen fro ball 10ft

Set at 7.5 ft from ball

ball to screen 10 ft

our elevation is 4000 where we live

set temp at 80 f

Ah, ok.

The elevation of 4.000 ft and temp setting is what makes the reading more accurate, and probably not the distance from the unit to the ball.

I would not expect the distance of 4 ft to work at all, but when You say hitting area the actual distance from the unit to ball is higher?

I've seen tests where distance below 6 feet starts to have issues, but never tried it myself.

The elevation is actual

Even if I set the elevation to 8000 at 7.5 ft behind ball no driver readings

4 ft behind ball at my actual elevation no problem or problems, Chips are also reading

shows my natural draw , also can fade as desired

Test yourself it won’t explode

So,

real distance: R10 moved 4 ft behind the ball; screen 10 ft from hitting area

settings: R10 7,5 ft elevation 4000 ft.

is it correct?

many thanks
