Given what you have already said about your professional training and experiences, I assume you are familiar with the concepts of standard error and regression to the mean. Even if (and it's a big "if") the scores you've reported from online tests or attempts at concordance tables were valid measures, standard error of measurement (and the resulting confidence intervals), as well as regression to the mean, would suggest that these two estimates of IQ are essentially equivalent.
