I looked into this a bit more and for example the electron mass they
predict (they dont quote an error so I assume the value is supposed to
be exact) is around 27 standard deviations from the measured value

The prediction depends on the Gravity Constant G among other
constants. AFAIK, G is has been established to only about
3 digits so far.

See http://www.heim-theory.com/downloads...rmula_1989.pdf
and http://www.heim-theory.com/downloads...ed_Results.pdf
page 12 in particular.

Also they predict a mass of an e0 ("neutral electron" apparently) at
similar mass to the electron. Yet this particle has never been observed
in any particle collider experiments to date.

AFAIK, nobody has yet looked for a neutral electron in the predicted
mass range.
