Recently I found out a website that can simulate your tier up chance.
https://www.sobtechs.dev/cubing.html
Below is the tier up rate for each cube in MapleSEA.
And it is also coming with a simulator which is not convincing as I use 363 appox additional cube in game, it did not tier at all. In MapleSEA, the rate up rate is hardly than you think or what the simulator shows you! You cannot rely on it but you can refer to the rate of tiering above as a reference.
