A few things to discuss...
First, you can apply a delay to refresh rate switching, if you let Kodi handle this task. To do this, turn off display mode switching in madVR or delete all of the display modes you entered. Return to Kodi, enable adjust refresh rate and apply the desired delay. Now Kodi handles the refresh rate switching. It doesn't matter if Kodi or madVR handles this task. In your case, it would be better to have Kodi handle this. Adding this option to madVR is on madshi's "To do" list.
As for your scaling question; everything looks fine. Read the "scale" line in the madVR OSD when playing 1080p files. This indicates what madVR is doing with the pixels. It says 0,0,1920,1080 -> 0,0,3840,2160. That is upscaling. I don't know how your projector handles this, if it is true 4K or not. But madVR is sending 2160p to the display. Given your rendering time of 26ms, you may even be able to increase your value of chroma upscaling to super-xbr or NGU low. I don't know about that, though.
Delete ShowRenderSteps in the madVR folder. This is only for debugging. It will slow down madVR performance slightly.
And the last issue is not easy to understand. All HTPC's have an issue with syncing the audio and video clocks during playback. This causes the video renderer to drop or repeat a frame every few minutes to resyncronize the clocks. These shouldn't be noticable. But, if they bother you, you can create custom refresh rates in madVR to improve the timing of the video clock in relation to the audio clock.
This may blow your mind with how technical it is, but the tutorial is here if you want to attempt to create your own custom mode: http://madvr.com/crt/CustomResTutorial.html.
