compression specs 102psi?

[Wpg Manitoba]

The compression specs listed in the inside of my cowling is listed at 7.2 kg/cm. This only comes to 102psi. I'm just a little confused cause that seems extremely low compared to other motors.
If anyone can explain this to me I would apreciate it cause to my understanding 100psi is just pinching it.

That is normal for a Yamaha 2 stroke engine.

So that would mean that 90 or even 80 psi would be reasonable compression for this motor?

[boats.net]

Compression neads to even, no more than 10% difference between cylinders. 80 would be low but will run on 90.

so would the compression spec of 102 psi be suggesting that this be the minimum compression?
