Auto doesn’t always select brown, but it will prefer brown over rectilinear/perspective.

So for my Phantom4 RTK (PH4 RTK) with uncorrected images, Fisheye slightly better than Auto oe Brown.

But something is very strange. With the exact same dataset, the horizontal and vertical accuracy are 2 to 4 times bigger with fisheye than brown. I have the same results with others dataset. The “brown” batch were computed few weeks ago, with the last ODM version at that time and I updated ODM for the Fisheye batch. Any idea ?  
Thanks
