I have been aware of this report for the last 10 years, and have a copy.
It might look impressive, but as a test report it leaves much to be desired. My main criticisms are:
[1] The test equipment used is not itemised and named. Thus we have no idea of the specification and accuracy of the test equipment.
[2] There is no statistical analysis. Measurements appear to have been made only once, so we have no idea of repeatability and statistical spread of results.
[3] The work was commissioned by Hi-Fi Tuning, and the report written by GMCOM Technologies GmbH not surprisingly endorses the use of Hi-Fi Tuning fuses.
Many of the differences measured between various fuses are likely to be within the accuracy of the test equipment. Some are inconsistent. Other test results are easily explained (such as the higher impedance of 'spiral' wound fuses compared with solder types), and some results are irrelevant (such as the impedance of fuses at MHz frequencies).
It makes for interesting reading, but I don't give it great import.

Me neither. I use Bussmann fuses because they work as a fuse

Be aware of Chinese counterfeit Bussmann fuses, especially those that supposedly conform to BS1362.

I've read some pointless crap in my time but that's right up there in the Top 5...
