Actually.... Looking at your numbers again:

+0.08786 +0.07386 +0.06711 +0.10086
--0.05364 --0.01064 +0.03186 +0.11586
--0.17089 --0.07164 +0.00086 +0.12311
--0.26139 --0.13414 --0.03164 +0.13261

It almost looks like your bed is warped. Look at how fast the numbers change on the right side column. They increase .01mm per sample. But on the left side, they are decreasing by .1mm per sample. That doesn't seem right and may be the explanation for your question.
