ProChrono Digital Chronograph question(Duplicate Velocitiy Indications)

[BD100]

Just purchased a ProChrono Digital Chronograph and have noticed I've been getting lots of "dup 1"(duplicate velocity) read outs. The original number is usually a whole number. For example 3350. I'll fire another shot and then get a "dup 1" indication. This happens quite often and I know it's just not statistically probable to have that many shots have the exact same velocity. I'm especially suspicious as the duplicate velocities are always whole numbers. Was thinking maybe the unit is designed to round up or down to the nearest whole number???

Anyone experience this issue with their Pro Chrono's?

The duplicate whole number signifies the number of duplicates, that is DUPLICATE 1 means 2 shots same velocity. DUPLICATE 2 means 3 shots same velocity.

I have a Pro Chrono also and the readouts are always whole numbers. I'm not aware of a method to get decimals on it. It's about three years old so maybe they have improved it since then. When mine reads duplicates the extreme spread is usually pretty low-so I trust it is reading correctly. I've compared mine to two other chronographs set one behind the other and they were within 1 foot per second of one another.
