I (and others) experienced the same. I think that this increase could be
explained by the fact that the 'returning' current coming from the
'radial-earth' and from the 'mains-earth' have different phase, so simple
'resistor-wise' paralleling of both earthsystems is not valid. If the
phase-difference between both currents is large enough the resulting total
current will be less than the current from 1 system only. Or said otherwise
the total resistance will increase instead of decrease.
Would be interesting if not only the currents in both earthsystems but also
their phasedifference could be measured.
