How can I properly fix my ranking system?

I have tried making a ranking system based on a players stat but this does not work properly. When I test this in game I have 30k SP and should have the Master rank yet I still have the rank after that which requires 50k This is the code :

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Modules = ReplicatedStorage:WaitForChild("Modules")
local Ranks = require(Modules:WaitForChild("Ranks"))
local CS = require(game:GetService("ServerScriptService"):WaitForChild("ChatServiceRunner"):WaitForChild("ChatService"))
local UpdateRank = function(Speaker, Player)
    local Leaderstats = Player:WaitForChild("leaderstats")
    local SP = Leaderstats:WaitForChild("SP")
    for key, value in pairs(Ranks) do
        local RequiredSP = value.RequiredSP
        local Color = value.Color
        local Name = key
        if SP.Value <= RequiredSP then
            local Character = Player.Character or Player.CharacterAppearanceLoaded:Wait()
            local Humanoid = Character:WaitForChild("Humanoid")
            local Head = Character:WaitForChild("Head")
            local Rank = Head:WaitForChild("Rank")
            local Label = Rank:WaitForChild("Label")
            Label.Text = Name
            Label.TextColor3 = Color
            Speaker:SetExtraData("Tags",{{TagText = Name, TagColor = Color}})
            break
        end
    end
end
CS.SpeakerAdded:Connect(function(Speaker)
    local Player
    Speaker = CS:GetSpeaker(Speaker)
    Player = Speaker:GetPlayer()
    if Player then
        local Leaderstats = Player:WaitForChild("leaderstats")
        local SP = Leaderstats:WaitForChild("SP")
        UpdateRank(Speaker, Player)
        SP:GetPropertyChangedSignal("Value"):Connect(function()
            UpdateRank(Speaker, Player)
        end)
        Player.CharacterAppearanceLoaded:Connect(function(Character)
            UpdateRank(Speaker, Player)
        end)
    end
end)

And here is the ranks module :

return {
    ["Noob"] = {
        RequiredSP = 0,
        Color = Color3.fromRGB(231, 234, 18)
    },
    ["Rookie"] = {
        RequiredSP = 100,
        Color = Color3.fromRGB(115, 115, 115)
    },
    ["Average"] = {
        RequiredSP = 1000,
        Color = Color3.fromRGB(218, 0, 3)
    },
    ["Expert"] = {
        RequiredSP = 5000,
        Color = Color3.fromRGB(10, 184, 236)
    },
    ["Grinder"] = {
        RequiredSP = 10000,
        Color = Color3.fromRGB(18, 188, 72)
    },
    ["Master"] = {
        RequiredSP = 25000,
        Color = Color3.fromRGB(68, 177, 136)
    },
    ["Legend"] = {
        RequiredSP = 50000,
        Color = Color3.fromRGB(255, 255, 0)
    },
    ["Heavy Grinder"] = {
        RequiredSP = 100000,
        Color = Color3.fromRGB(54, 54, 54)
    },
    ["Unstoppable"] = {
        RequiredSP = 250000,
        Color = Color3.fromRGB(115, 0, 1)
    },
    ["Hacker"] = {
        RequiredSP = 1000000,
        Color = Color3.fromRGB(0, 255, 0)
    },
    ["Amazingly Good"] = {
        RequiredSP = 5000000,
        Color = Color3.fromRGB(158, 0, 197)
    },
    [":)"] = {
        RequiredSP = 10000000,
        Color = Color3.fromRGB(0, 0, 0)
    },
}
