So, you believe that a false explanation can have better quality than a true
one? I am not convinced to this idea. Namely:

1) We are absolutely sure that some phonetic processes are irregular. See my
other posts for examples. In other words, creating any conditions for an
observed change is sometimes impossible. In given conditions a process
sometimes took place and sometimes it did not.

2) Naturally we may ignore such phenomena, and build theories which ignore
facts (existence of irregular processes is a fact, not a hypothesis). But
the question remains: will our expectation be more plausible then?

All depends on the question. When we are searching for an answer to the
question whether a given word in one language is related to another word in
another language, statistics will not help us much. For example, let the
question be if the Polish "pokrzywa" (nettle) is related to Czech kopr^iva.
There is not such a rule that kop- > pok-. There are also no words with such
a change. Using strict methods based on neogrammarian rules we should state
that the words under question are not related. But if we stated so, we would
be wrong. They are related. We simply know it from different sources than
language analyses (the old form "koprzywa" remained in Polish place names,
and it can even have survived in dialects, I'm not sure; anyway, it has been
recorded many times in the past (in fact, the "spoiled' form "pokrzywa"
appeared only in 17 century, and it is present earlier in dialects).

OK, and what if we have not other sources? Cretan adeuphos, Modern Greek
aderphós, Attic adelphós all mean "brother". We cannot formulate a strict
rule for l > u in Cretan or for l > r in Modern Greek. Should we believe
that all these three forms are similar in form and meaning only by chance?

And, should we reject the hypothesis that Modern Greek alepou "fox" is a
continuation of the Classic aló:pe:ks? In fact, there are no rules for o: >
e and -e:ks > -ou [u]. Should we come to the conviction that both words have
absolutely nothing to do with one another?

And finally: are Greek bdella and Latin hiru:do (both meaning "leech")
related? From Neogrammarian point of view, they cannot be. But both of them
have the same meaning. Yes, they look very different. But the stem "to
suck", their guessed source, has so many different variants in IE that many
various irregularities are possible in related forms. Should we reject the
hypothesis of relationship between the two forms?

My answers to these questions are easily predictable.
