HF Allocations: Shortwave Broadcast v. Amateur Radio

I was just curious what percentage of the HF band is being used for Shortwave Broadcast versus Amateur Radio. Here's what I came up with:
Shortwave: 6.145 MHz [1] or 22% of the HF band [2].
Start End Bandwidth
25.670 26.100 0.43
21.450 21.850 0.4
18.900 19.020 0.12
17.480 17.900 0.42
15.000 15.825 0.825
13.570 13.870 0.3
11.500 12.160 0.66
9.250 9.995 0.745
7.100 7.600 0.5
5.800 6.300 0.5
4.400 5.100 0.7
3.900 4.050 0.15
3.200 3.400 0.2
2.300 2.495 0.195
The 41m shortwave band is being changed. The 75m shortwave band is not used in all Regions and is shared with amateur radio.
Amateur radio: 3.75 MHz [3] or 13% of the HF band [4].
Start End Bandwidth
28.000 29.700 1.7
24.890 24.990 0.1
21.000 21.450 0.45
18.068 18.168 0.1
14.000 14.350 0.35
10.100 10.150 0.05
7.000 7.300 0.3
3.500 4.000 0.5
1.800 2.000 0.2

The 80m amateur radio band is not used in all Regions and is shared with amateur radio. Also, the 60m frequencies available to US and UK amateur radio operators are not included.

I wonder what the other ~78% of the HF band is being used for.
