Hello, so I need some help understanding all the numbers and that with a motor analyzer. I purchased the sky rc one to start to understand it. Any suggestions would be appreciated thanks in advance.

You're going to get a bunch of replies contridicting each other. I follow Nick Adams on Youtube. He still recommends maxing the timing to 6 amps and locking it down. Look him up. Also run a fan and get a temp gun.

Measurements as it relates to understanding a motor

current-induces torque in the motor. the efficiency of this current to force inducing measurement varies. at most probably 70% efficient on a curve starting at 1 to 70 then back down to 1. Efficiency can be limited by over or under timing. friction, inertia, and mechanical efficiencies add to or remove current.

voltage-the higher the voltage the higher the rpm can go. the opposite is true as well.

timing-the rotor has a magnetic center on each magnetic pole. the timing is the distance the centerpoint is from the sensor that senses it. there are 3 sensors and more than 1 pole.

Kv-RPMs per volt or a prediction of max rpm.

Db-sound pressure of the motor

cant tune everything to 6amps. My Schuurspeed v4 tunes at 3.5. I know theres a lot of motors out now that tune to @ 3 now.
The more I have an analyzer the more I think it's pretty worthless. It's good to get an initial tune on it I guess but with gearing, timing boost etc, it doesnt do a whole lot of good. Maybe to do motor comparisons like Nick. I used to do quite a bit of tuning on them, but not so much anymore. I almost blew up a motor once cuz I tuned it to 6amps. I think it was an smc. Yeah, no bueno.
I use it to just get a base setting then go from there. I guess that doesnt answer your question lol!! Sorry.

I bought one but still do not fully understand the numbers or what I'm should be looking for lol

call the motor mfg and ask them what timing and Kv they recommend for your setup. Ask them a starting point for gearing.
