Pro Chrony Beta vs Caldwell Ballistic Precision chronographs (data)

I shot my Pro Chrony recently and it still works but needs the trajectory to be very close to and right in line with the sensor. It was getting really tedious accommodating it all the time so I got a Caldwell. Wanted to see how the new Caldwell compared to Pro Chrony. I set them up with the Caldwell about a foot from the muzzle and the Pro Chrony a few inches behind the Caldwell. Both had lights on them. I was indoors with fluorescent on in the room. I shot 30 rounds from my 177 regulated Marauder and here are the results. IMHO the Caldwell looks better cause it has a flatter trendline while the Pro Chrony has the downward trend.
The Caldwell comes in a zippered soft case that holds the chrony, lights, data cable, shades, tripod (in its own soft case), 12v power adapter and battery case for lights. The last pic is the data file recorded from the Caldwell on my android phone via the data cable. The app saves the data as a txt file that needs a little work to use in excel but it can be saved most anywhere on your phone including dropbox. Then the data file appears on my pc in seconds.

I have been looking at the Caldwell, I like the data cable idea..
I wonder what was the cause of the error shots (20,000+FPS)

I make 2 predictions;
ON THE DATE WHEN US TROOPS ARE ISSUED AN Energy Pulse Weapon,
1. The US Soldier will have on his person a version of the Colt 1911.
2. He will be aiming the NEW Weapon at someone carrying an AK47.

I think those readings are cause of poor lighting.
I'm going to redo the test w/o the fluorescent lights on.

I thought that may be the case, but wanted your thoughts since it was you work.
Can you. Imagine the "RPM's" that pellet would be spinning?(if it was a valid speed reading)
I don't know the twist rate of your rifle, but assuming a 1 in 16 inches,
At 874 FPS equates to about 39,330 rpm..
As your pellet is leaving the barrel.
Hard to believe a little .177 lead pellet can hold together at that spin rate..

I shot over both chronographs indoors and out. Indoors I switched to incandescent room lighting and still using the LEDs for chrono lighting. It looks like the Caldwell under its IR LEDs reads high. Outdoors the Caldwell read slightly below the Pro Chrony. But indoors the Caldwell is consistently higher than the Pro Chrony. The Pro Chrony data averages nearly the same whether indoors under white LEDs or outdoors under the sun.
When I was trying to find alternate light source to my flourescent room lighting I tried LED headlamps. On low power the dithering drives the caldwell nuts. 4 digit numbers flash rapidly on the screen.
The Caldwell also has a USB type B port that is labeled in the manual as 'factory use only'.
