I have inherited a golf pool spreadsheet (see below) for the Masters. You initially pick 10 golfers for the tournament on the assumption that some (even Jordan Spieth!) will miss the cut. The 6 best golfers of your picks after the cut have the difference in their score from the tournament leader added up for all 4 rounds. If you don't have 6 golfers who made the cut you're out of the pool. deChambeau didn't get much love from our group this year!

You can see in cell I3 that currently Player 1's golfers are 24 above deChambeau, with Koepka and Morikawa having not finished Round 1. Invalid or missing rounds leave the Actual Total column at 0.

The SUMPRODUCT function in I3 works fine.
Excel Formula:
=LET(
     ScoreDifference, SUMPRODUCT(
        NOT(ISBLANK(tblResults[Player 1])) * (tblResults[[Actual Total]:[Actual Total]]<>0),
        tblResults[[Actual Total]:[Actual Total]] - Leader_Score),
    Result, IF(ScoreDifference = 0, 999, ScoreDifference),
    Result
    )
But in order to handle the cut from 10 to 6 players it is necessary to eliminate the "x" against the dud players, although one can just stop reporting the scores on the others. But since I just copy the round numbers from the ESPN scorecard into the spreadsheet I either blank out every non-pool golfer or delete the "x".
I'd like a simpler way to recursively calculate the SMALL function using the # Selections value in F3. I'm new to LAMBDA functions but I'm hoping there's a way to actually do something in the pseudo-code below...
Excel Formula:
=LET(
    ScoreArray, -get the Actual Total array for the Player-
    SmallTotal, Recursive LAMBDA(RunningTotal, SMALL(ScoreArray,6...1),
    RunningTotal
)

Any chance of this? Thanks.

Excel Facts

What is the last column in Excel?
Excel columns run from A to Z, AA to AZ, AAA to XFD. The last column is XFD.
BTW, My LAMBDA attempt is getting a #VALUE error, probably because I don't understand how to properly record the variables.

My LAMBDA function is defined as FindSmallLambda in Name Manager as
Excel Formula:
= LAMBDA(SmallValue,Data,IF(SmallValue>0,FindSmallLambda(SmallValue-1,Data,SMALL(Data,SmallValue)),0))

And the cell calling it has
Excel Formula:
=LET(
    ScoreArray,  NOT(ISBLANK(tblResults[Player 1])) * ( tblResults[[Golfer Total]:[Golfer Total]] - Leader_Score) * (tblResults[[Golfer Total]:[Golfer Total]]<>0),
    RunTotal, FindSmallLambda($F$3, ScoreArray),
    RunTotal
)
