Your rocket had considerable speed at apogee. The simulation had zero speed there - indicating a vertical simulation. The rocket turned more than the simulation predicted (vertical simulations don't gravity-turn at all, actually) indicating any combination of the following:
1) Launcher whip
2) Weathercocking
3) A launch angle not perfectly vertical
4) Something else like that there
Actual ascents are rarely near-perfectly vertical. That said, the correspondence isn't bad.
Think of it this way, if you launch it again, you'll get different numbers. A simulation cannot be more predictive than real-world variability.
Your apogee numbers are pretty close. The velocities don't match up well; are the units the same?
Looked at it a little more. Did you have an early deployment? Looks like you might have still been going up when it deployed. That may account for the lower altitude than the sim; although you are only off by about 50 feet or so. Hard to read the simulation graph.
You lost me there. I am seeing a velocity of just over zero at drogue deployment.
?? I'm seeing ~425 fps at apogee - just shy of 8 seconds ??
I see it too. But the velocity is derived from barometric data on the RRC3 so I wouldn't put too much faith in it. The pressure altitude data does show something happening at about 7 seconds which is well before apogee. Motor ejection perhaps.
