Fix frequency accumulation again

Browse Source 
This is a revert of commit 99d18abf updated for later changes. It seems
in that commit the calculation was changed to match the reversed dfreq
added in 1a7415a6, which itself was calculated incorrectly. Fix the
calculation of updated frequency and matching dfreq.
