Tons of datastore throttling errors?

SaveData = function(plr)
    local ls = plr:FindFirstChild("leaderstats")
    local saveready = plr:FindFirstChild("SR")
    if ls ~= nil and saveready ~= nil then
        if saveready.Value == true then
            local Coins = ls:FindFirstChild("Coins")
            local Level = ls:FindFirstChild("Level")
            local EXP = plr:FindFirstChild("EXP")
            if Coins ~= nil and Level ~= nil and EXP ~= nil then
                local tableofstats = {
                    Coins.Value,
                    Level.Value,
                    EXP.Value
                }
                local function AttemptSave()
                    local success, msg = pcall(function()
                        GetData = PlayersStats:GetAsync(plr.UserId)
                    end)
                    if success then
                        if GetData then
                            pcall(function()
                                PlayersStats:UpdateAsync(plr.UserId, function() 
                                    return tableofstats 
                                end) 
                            end)
                        else
                            pcall(function()
                                PlayersStats:SetAsync(plr.UserId, tableofstats) 
                            end)
                        end
                        return true
                    else
                        return false
                    end
                end
                local savetest = AttemptSave()
                if savetest == false then
                    wait(10)
                    local savetest2 = AttemptSave()
                end
            end
        end
    end
end

This is my datastore script, I used to have an autosave function in a while wait(120) loop (every 2 mins) and when the player leaves and I got tons of errors with datastore throttling and data loss reports which was confusing me because when I looked at the budget everything seemed ok. Now I'm only saving when the player leaves but there is still lots of datastore throttling errors and I get reports of data loss. What am I doing wrong? Thanks
