Formula newbie, find highest 5 numbers in a rollup array and add together

[Darren_Taylor]

Hi, I’m a bit new to this and not sure if it’s even possible.
I have a table of ‘scores’ with multiple ‘players’. Each player has a score, up to 30 scores each.
In another table I have a rollup which displays all the players scores.
What I’m trying to do is find the 5 best scores for each player, add as a total, then divide by 5 to give an average score for each player. This should then give a leaderboard of the best players based on their 5 best scores out of X scores.
I’ve managed to do this manually in Notion by adding a checkbox formula which when I enter the player score, I look at their top scores and check/uncheck as required. This is fine and works but I’m now looking to make it more automated with Airtable.
Is this dooable as a formula or better as a script on a front end with js?
So with airtable it works like this
‘Overall Score’ = All Scores + Checkbox = Total Score
Average Score = Total Score / 5
Thanks in advance.

Rollup fields can be set to only include records when conditions are met. You can set it ti where the checkbox field is not empty, and sum values from the Score field.

This works great by the way, thanks. Would be even better if I could automate the checkbox.

[Kamille_Parks]

You could add an Automation Script Action to calculate and set the checkboxes for you.

Automation Script Action

Thank you. I’ll read up on that.
Thanks again for your help.

Here’s a script which should be of use. It assumes you have a script input called playerName which reports the Automation’s triggering record’s value of the Player name:

const table = base.getTable("Name of table where scores are recorded")
const query = await table.selectRecordsAsync()
const records = query.records

const inputConfig = input.config()
const playerName = inputConfig.playerName

const sorted = records.filter(x => x.getCellValueAsString("Name of field linking to Player") == playerName).map(x => {
    return ({
        id: x.id,
        score: x.getCellValue("Name of score field")
    })
}).sort((a,b) => {return b.score - a.score})

const top5Scores = sorted.slice(0, 5)
const otherScores = sorted.slice(5)

table.updateRecordsAsync(top5Scores.map(x => {
    return ({
        id: x.id,
        fields: {
            "Name of checkbox field": true
        }
    })
}))

table.updateRecordsAsync(otherScores.map(x => {
    return ({
        id: x.id,
        fields: {
            "Name of checkbox field": false
        }
    })
}))

This should reassign the checkboxes whenever the Automation runs.

Thanks again for this. I’ve tried every combination, and even started again with a new table but, I get the same error.
Error: Request parameters failed validation.
at main on line 27
Here’s my amended script
const table = base.getTable(“Game Two”)
const query = await table.selectRecordsAsync()
const records = query.records

const inputConfig = input.config()
const playerName = inputConfig.playerName

const sorted = records.filter(x => x.getCellValueAsString(“Player Name”) == playerName).map(x => {
return ({
id: x.id,
score: x.getCellValue(“Points”)
})
}).sort((a,b) => {return b.score - a.score})

const top5Scores = sorted.slice(0, 5)
const otherScores = sorted.slice(5)

table.updateRecordsAsync(top5Scores.map(x => {
return ({
id: x.id,
fields: {
“Check”: true
}
})
}))

table.updateRecordsAsync(otherScores.map(x => {
return ({
id: x.id,
fields: {
“Check”: false
}
})
}))

Like I said, I’m pretty new to this so appreciate the help.
thanks.

Replace the two table.updateRecordsAsync() functions with this:

await table.updateRecordsAsync(top5Scores.map(x => {
    return ({
        id: x.id,
        fields: {
            "Check": true
        }
    })
}))

let updates = otherScores.map(x => {
        return ({
            id: x.id,
            fields: {
                "Check": false
            }
        })
    })

while (updates.length > 0) {
    await table.updateRecordsAsync(updates.slice(0, 50))
    updates = updates.slice(50);
}

Sorry, still erroring on 18. Same error.

Error: Request parameters failed validation.

Thanks for the help again.

How did you set up the input variable? It should be pulling from the {Players} field, the same field being used in the .filter(). Assuming {Players} is a Record Link field, and your input variable is set to Field values | Players | List of 'name', try replacing the filter:
filter(x => x.getCellValueAsString("Players") == playerName)
with:
filter(x => playerName.includes(x.getCellValueAsString("Players")))
