I need help with a jump leaderboard?

Hey huys, I have this script:*

game.Players.PlayerAdded:Connect(function(player)
		    local leaderstats = Instance.new("Folder")
		    leaderstats.Name = "leaderstats"
		    leaderstats.Parent = player 

		    local jumpCount = Instance.new("IntValue")
		    jumpCount.Name = "Jumps"
		    jumpCount.Parent = leaderstats

		    player.CharacterAdded:Connect(function(character) 

		    local humanoid = character:WaitForChild("Humanoid")
		    local debounce = true

		    humanoid:GetPropertyChangedSignal("Jump"):Connect(function()
		    if debounce == true then
		    debounce = false
		    if humanoid.Jump == true then
		    jumpCount.Value = jumpCount.Value + 1
		    end
		    wait(0.2)
		    debounce = true 
		    end
	    end)
    end)
end)

And my problem is, when I spam the spacebar, the leaderboard increases when the character has not made all his jumps (for example: I spam 10 times so the leaderboard is at 10 but the character has only made 5 jumps in the game) I hope someone can help me !

Obviously, the jump wait time (.2) is obviously not enough time. The whole duration of a jump is about 520 Milliseconds (.52 Seconds). This does not count for higher jump power, or/and higher jump height.

I'm in a rush so no time to explain it well, and might get stuff completely wrong. If this doesn't help, don't mind it.
