Better should consider growth over time as well.  I have made a decent
living tweaking developer code against the back end because a hundred rows
acts this way by 100 thousand acts differently.

In this situation you may find that you can do your sum statement on the
entire table with the where clause keeping only the few needed within the
dataset, then join back to that in your update statement.  Putting
functionality to sum another table by a single row's params in this table
receiving the update is not usually a good idea.
