It looks like you have slipped a decimal point somewhere (also that "ps" label is wrong).   I have an M8N running here and the report sawtooth errors are all within a +/- 10 ns span.   (and LEA-5T is +/- 5ns).

---------------------------

> Class: TIM(0xd) ID: TP(0x1), len: 0x10
tow:1519310.000000000 qErr:-0.000000048400 ps, week:2002
  flags:0xa refInfo:0x0
      is GPS, UTC available

Which says the next PPS is going to be -48.4 nano seconds out.  Similar
to the 52 nano seconds quantization error of a RasPi 3B.
