No wrong, but could be right.
It is a rolling 180 days not 6 months
So if you are in the Schengen area for Jan 1 as day one, and leave on 31st Jan and leave for 31 days, you can return to the Schengen area, you can stay for 59 days.
But is you stop all Jan leave (31), no days in Feb, all March (31), no days in April, in May you can stop 28 days (90-31-31 = 28)
Day 181 is I think June 30, so you can return and stay 31 days as the days you were in the Schengen area in January drop out of the 180 day window
You can adjust these days to suit yourself it is about 50% of any month, if you want to come and go, it is 50% of a rolling 180 days, if you want to be in the Schengen area for 90 days you can do but you cannot return until day 181.
Sounds more complicated than it is, I assume when you visit your passport will be stamped as you will be using the non EU line, in the past it was empty now it will be full.
