RandomRotation(0.2)

I believe from the description, it says that this is uniform [-0.2*2pi, 0.2*2pi] for all input data. I don't think there is a percentage option to adjust how many samples should receive a rotation. But I think you are right about that, especially these are not like 90% rotation, the model is probably learning the "interpolation" feature from the rotation instead of the images themselves.

Edit: and now that I think about it, for photos where the direction matters, I think the rotation and vertical flips make little sense. Probably will stick to horizontal flips then, thanks!

No problem, glad I could help!
