How to store a highest variable and add to leaderboard stat?

So, I've got a game where you fling yourself off a ramp. I've got some code to detect magnitude and put it into a leaderstat, but I want to find the highest magnitude before death, and then add that to the leaderstat. Sort of like a currency system. Below is the code for the magnitude stat that I currently have.

local Players = game:GetService("Players")

local point = workspace.Wedge

local function find_distance(speed: number, character: Model)
	local player = Players:GetPlayerFromCharacter(character)
	local root_part = character:WaitForChild("HumanoidRootPart")

	local leaderstats = player:WaitForChild("leaderstats")
	local magnitude = leaderstats.Magnitude

	magnitude.Value = (root_part.Position - point.Position).Magnitude
end

local function character_added(character)
	print(character.ClassName)
	local humanoid = character:WaitForChild("Humanoid")

	humanoid.Running:Connect(function(speed)
		find_distance(speed, character)
	end)
end

local function player_added(player: Player)
	player.CharacterAdded:Connect(character_added)

	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player 

	local magnitude = Instance.new("IntValue")
	magnitude.Name = "Magnitude"
	magnitude.Parent = leaderstats
end

Players.PlayerAdded:Connect(player_added)

I don't have a perfect match but..

local magnitudes = {}
local best = nil
local score = 0

for i,v in pairs(magnitudes) do 
	if v.Value > score then
		score = v.Value
		best = v
	end
end

print(best.."  Had the largest value, with a magnitude of "..score.." !"

You'd need to store all the magnitude in a table and then run this with "score" being the largest magnitude!

local magnitude_record = leaderstats.Magnitude
local magnitude = player:DistanceFromCharacter(ramp)

if magnitude_record.Value < magnitude then
    magnitude_record.Value = magnitude
end
