I must have explained it a half dozen times now. Do you really want me to post it again?
Generally, when a table lists split and stand expected returns, you multiply either of the listed expected returns by initial bet size to get overall expected return. The expected returns in the table take into account everything. You do not need to multiply the split value by 2, 4, or some other number. You use the value that is listed. If you choose to multiply split results by some number and do not multiply stand results by the same number, your results are invalid.
One exception is the table you found that seems to list values according to expected return per split hand. In this case, you need to multiply by the average number of hands with the listed resplit rules. Note that this average is not 2 (when there are resplits) and it is also not 4. It is about 2.62, with some variation depending on decks and num resplits.
