Okay, sorry to hear about the issue you have been having, hopefully some experimentation with the environment will yield positive results.
One should expect accuracy to me at least to focus on the circle. the angle of accuracy is approximate to the nail of your small finger from a distance of 30cm or so from the eye tracker (which is a biological not technological limitation of eye tracking) so it is unrealistic to expect a perfect focus on the circle’s dot.
