Hero Black 7 Bitrates?

What are the bitrates for the Hero Black 7 at each resolution for both video files with protune on and off?

 

The site's listing of Hero 4 bitrates is outdated both on resolutions and lack of HEVC.

I found an app that shows bitrate so here are the ones I use the most:

 

4K 60fps HEVC ProTune on - 78Mbps (no H.264 option) or about 7 minutes in a 4GB chapter

4K 60fps HEVC ProTune off - 60Mbps (no H.264 option) or about 9 minutes in a 4GB chapter

2.7K 60fps HEVC ProTune on - 60Mbps (vs 60 in H.264) or about 9 minutes in a 4GB chapter

2.7K 60fps HEVC ProTune off - 45Mbps (vs. 60 in H.264) or about 12 minutes in a 4GB chapter

1080p 60fps HEVC ProTune on - 36Mbps (vs 45 in H.264) or about 15 minutes in a 4GB chapter

1080p 60fps HEVC ProTune off - 24Mbps (vs 30 in H.264) or about 22 minutes in a 4GB chapter

720p 60fps HEVC ProTune off - 24Mbps (vs 30 in H.264) or about 22 minutes in a 4GB chapter

 

I don't understand why the 720p bitrate is so high. GoPro could have easily dropped to 12mbps for a compariable bitrate to the twice as large 1080p and offered a smaller file size option for customers that want it. For reference, that would be about about 44 minutes in a 4GB chapter. Or put another way 90MB each min instead of 180MB. It seems silly to have the same file size for half the resolution, and there are times when smaller file size is advantageous.
