there are no readily available statistics to answer that question.

Unfortunately, unless one knows the total number of movements of both
experimental and other aircraft, as well as the absolute numbers of accidents
for both, the latter alone isn't of much use.

we are working up the statistics on percentage of experimental aircraft vs
other aircraft based at the airport, and also the percentage of training, vs
local vs transient.

Movements would be much more cogent than the number of aircraft based at the
airport.

Many accidents in the past have involved transient pilots not familiar with
high density altitude operations or desert wind conditions.

Which airport is this?
