B737 Cabin pressurizes very strangely

Hello developers,in all models of the 737 the two pointers of the cabin pressure gauge seem to indicate just the value that the other pointer should.e.g. flying at FL380 the Cabin altitude is 20.000 (poor passengers) while the diff. Press. is 3 psi (should be much more).Looking at the gauge, it seems that the short pointer indicating the cabin alt on the inner scale shows the value of the diff. pres., which has to be read on the outer scale and vice versa.It's not a big issue, but looks rather strange though.Greetings from Germany,Philipphttp://www.precisionmanuals.com/images/forum/800driver.jpg
