As I currently see it, there are two types of computed values: 1. Sums of balances of move lines with an account belonging to a specific account or account type selection. For balance sheet type of accounts the sum goes up to specific financial period, for profit and loss type of accounts the sum goes over a period range. 2. Some arithmetic operations with the values calculated from 1 or 2. As the expensive part is already done by the database it would be possible and convenient to use a Python expression here.
