Yes, Xentry only use Crank-Pos sensor speed to generate those readings of cylinders cranking speed but its kinda accumulated averaged out reading from very first second to 6th second.
The first 0.5 sec reading is slower than the rest of the 5.5 sec reading, which already overcame the locked rotor current and then able to spin at maximum starter speed ( based on battery health ) already.

After all the Hyundai bat sensor is only 102Amp max reading , so Xentry can not combine voltage/current based calculation.

If the engine is at 30 Celsius like mine and not been started for 30 days, I would need to do , best if 3 times compression test, to get the oil better distributed and best maximum cranking speed can
then be achieved at 4th test. This Mobil 1 current SP formula seems to be able to cling to metal better than older formula at 30 days no activity.
Once I got a decently low RPM cranking test speed and higher differences between cylinders at 44 days no engine activity at first time Comp-Test, when using older Mobil 1 formula.

These tests now, I use current clamp at STARTER positive cable and not at main 1st ground cable at suspension tower to negative battery post.
Main 1st ground cable will read all combined load including ECM and etc etc and would be approx 20 ish amps more, that is why some of my Pico file can show 200ish amps, if I use that 1st main ground instead.

If we use INRUSH reading capable current clamp to see peak current, it has to be clamped at STARTER positive cable, as the clamp can only work with zero current as baseline and then the inrush spike thereafter
can then be registered.

Easy bro, Prihadi's cool. Huge contributor to the forum.

Even with this thread, he's following up with long-term data on a subject him and I brought up a few YEARS ago. Super cool! No one does that.
