@DogWithBigEars,
Not exactly. The reasons why have been debated endlessly here and on his page; but the data is pretty clear - eventing has gotten more deadly over the years, not less. Yes, so of the fences from the 60s, 70s and 80s that are pictured are crazy looking to our eye, but the fact of the matter is, there were fewer falls and fewer deaths, both in aggregate and as a percentage of competitors.
When you boil down all the opinions and theories, the reasons comes down to 1.) Change from long format to short format. Horses are less fit, conditioned differently and upper level horses are selected for qualities other than stamina. 2.) The change in the scoring formulas which lead to dressage becoming more important. Event horses used to be horses that could gallop, jump and get through the dressage; now they’re dressage horses that can gallop and jump. 3.) Related to 2.)- the move away from the TB and to the WB. 4.) The change in sport from primarily amateur to primarily professional, with the concomittant need to advance horses through the levels, have multiple riders do the conditioning and to enter multiple horses at a single competition.
So you can call Denny a hypocrite about some things, and criticize him for others, but there is no hypocrisy in calling out what’s dangerous today while posting old competition photos.
