[Stere]

Drier in summer i think?

In general, the weight of a load of summer-cut (June-July) birch and aspen can be
estimated by assuming that half the weight is water. Wood cut in January or
February has more moisture and could be 6 or more percent heavier than the same
volume cut in summer.
Moisture content will vary from year to year so you should calculate it for individual
cases if you wish to be precise. In addition, if you want to compare the weights of
winter-cut and summer-cut wood, the samples should include equal proportions of
top, middle, and bottom logs because of moisture content variations within the
tree.

Furthermore, moisture content of live trees varies with the season. With downy birch (Betula pubescens) it is highest in the spring, just before the breaking of the buds and lowest in the summer. With Scots pine (Pinus sylvestris) the moisture content is highest during the winter and lowest during the summer [3], [4], [5], [6].

This is just spinning my whole world around, man.

i like the idea of a check-table of chip weight, but i fear it wooden work

Some serious myth busting there. I stand corrected.

What else are we mistaken about?

 

Are we going to have to get back into the covid thread?!

Lower water content in summer causing the wood to shrink (and hence build internal stress) is my pet theory for cause of summer limb drop, but obviously no backing for that.
