This paper experimentally verifies that an asymptotic result on the size of the image for Icart's hash function provided by Fouque and Tibouchi is true for small primes less than 2^{19} and for all curves of conductor less than or equal to 100. Combined with Fouque and Tibouchi's asymptotic result, this proves that the coverage of Icart's hash function is a 5/8 fraction of the points (with some error).
