actually, try to go back to the details from 2021/22 if you can and make sure you have the right cost prices/amounts to base this calculation on, and understanding of how this situation occurred, why they would have cost basis on the larger lots but not the smaller lots with the same acquisition dates. It's odd to me that the share count if you take all the lots with more than 9 shares you get to the 51.0691 exactly as reported, but the cost basis for that population based on these prices doesn't add up to what is reported.
