Agreed - and in proportion to the number of competitors, I would guess that the fatality rate is less than, say, climbing K2.
Update: Summing the 'number of finishes' column in the Competitor Analysis' on the IOMTT site I get 17355 finishes (the data appears to cover competitors who have finished 6 or more races.) The above-mentioned Wikipedia list of TT fatalities page gives a total of 281 (including 16 non-rider fatalities), giving a BoE figure of 1.62%. In contrast, the Wikipedia 'List of deaths on eight-thousanders' page says that, as of August 2023, about 800 climbers have summited K2, and 96 have died trying.
Annapurna has the worst statistics among these mountains: "for decades, it has the highest climber to fatality ratio of around 32%".
For the TT, if you think the number of competitors rather than finishes is the correct figure to use, the TT list used above contains 1275 competitors, for a fatality rate of about 22% (though, as mentioned above, this seems to exclude competitors with fewer than 6 finishes.)
