Use a small example
Open the hand calculator and keep the starter separate. Choose one category to inspect first. Read every listed combination and identify the physical cards it contains.
Keep a scratch list
Write each combination once. If two entries look similar, compare the actual card identities rather than only the rank names. A repeated rank can make two combinations distinct without making one card appear twice within the same combination.
Compare the categories
After checking the list, add the category subtotals independently. A correct final number reached through incorrect components is still an explanation worth fixing.
Keep the result bounded
This is an original study routine, not an official counting script. It does not establish that the hand was dealt, discarded or played correctly.
