I translated my last test for you. I think it's worth it.
Are you sure that your machine works well with a high leak? What leaks are acceptable? Are the Chinese machines as good as the leading manufacturers? Which CPAP is the best having regard to those criteria?

Nice work!
Do you know why the high-quality full-sized machines all output 14.65 instead of 15 and 19.55 instead of 20?
Could this be systematic measurement error?

maybe… each CPAP has a 0.4 to 1 cm possible error according to the specifications (ResMed and Philips 0.5 cm H2O)
the measuring device was calibrated and its accuracy is 0.1, when the indications were fluctuating, then we note 0.05

Your 'large leak' test is absurd.
Sure, if you have a leak that's higher than the machine is spec'd to tolerate, it's *not going to tolerate it*.
