I will say one thing. Prunus species do not tolerate improper pruning.
Small mistakes make big problems for the trees. Improper pruning greatly
reduces living parenchyma cells which store carbohydrates in the form of
starch. This starch is converted to glucose for defense and many other
features. This is greatly reduced by flush cuts and stems left long.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

The longer you leave them on the tree, the sweeter they become. Timing
is
critical, so if you leave them too long, they get spongy. You can pick
them
a little early, if bugs are a problem. Leaving them at room temperature
will

improve their flavor (mostly by eliminating the unripe taste, but not
necessarily
the sweetness). Don't refrigerate them until after they have rippened.

Not sure what variety of plum you have, but I would wait at least until
they
are
red all over. They may still be partially unripe. Check that they are
not
hard
but pick before they turn spongy. Of course, tasting a few is always a
good
test.
Depending on the variety, there are no fixed criterias, but you will
develop
your
own criterea from experience. You should also address the bug problem.
Identify
the bug and take preventative measures. Are these bugs wasps? If so,
wasp
traps
may help.
