The last time I tried, it seemed to have a hard time targeting the floor tiles. I just assumed it was my house tiles that were giving me the issue.
I usually train shadow jumping in Serpents Hold. The hall there has 4 rugs. I get onto one of the corners and set up a UOA macro for 4 jumps in a row, 1 to each corner.
Easier than training outside and I rarely see a soul come in and see what the noise is.
