Huh? It has been *OVER A CALENDER YEAR* since I gave you the
exoplanet.eu link that has the catalog of exoplanet data, including
their masses.
Is there a particular reason you were not able to download the data
and perform your own analysis?

We have discussed this before.
When our ability to observe exoplanets is very strongly biased towards
large mass exoplanets, you are going to get a spectrum that peaks
around "large massed exoplanets".

So we have the Kepler planet finder, whose primary data product are
planets in that range. That plus the previous 20 years of planet
finding which is biased to Jupiter class worlds.
Is it that surprising to you that the data behaves in this fashion?

In reality the dearth of exoplanets below 5 Earth-masses is a big surprise to conventional assumptions (which are based largely on 'what you see locally is what you will see globally'). The huge sharp peak at 10-20 Earth-masses also confounds conventional astrophysics.

Again, is this due to there being an actual lack of planets in that
range?
Or is that simply because of what our instruments are sensitive to?

Note that this was a definitive prediction that was prior, feasible, quantitative, non-adjustable, and totally unique to Discrete Scale Relativity.
Really, 17? Your numerology predicts that? Can you show us how your
numerology predicts 17 rather than any other integer?
Additionally, given the number of "definitive predictions" of yours
which have been falsified why are you still looking for datapoints
that support you?

Robert, I gave you a link to all the known exoplanets via an exoplanet
database. Given that all you are looking for is a peak in the mass
data, why couldn't you have done this a year ago when the data was
given to you?
Why are you not actually doing any of the parts you claim science is
all about?
