Here is another indication of what is going on regarding the distributions of exoplanet parameters.

The Kepler mission has a huge bounty of exoplanet candidates and they are now checking to see which ones are actual planets (as opposed to other types of variable systems or transients).

The important point for this discussion is that they have published a histogram of the exoplanet candidates' radii. There is a single overwhelmingly dominant peak in the Neptune radius range.

When you combine the mass results of Mayor/Queloz with the radius results of the Kepler team, then I think you have a fairly strong argument that Discrete Scale Relativity's prediction of 8 x 10^-5 solar mass for the dominant peak of the exoplanet mass spectrum is being vindicated.

At this point I am not yet claiming total victory on this particular prediction (one of 14 definitive predictions, of which 4 are verifed or very strongly supported). However, one can see the light of knowledge rapidly approaching down at the end of the long dark tunnel.

Perhaps we need to 'refute and move on' from the old failing assumptions.
