Why does this not use exact formulas?
The reviewed sources contain panel values, but do not establish the full progression or Luck formulas. The planner therefore suggests interfaces to inspect rather than an optimal spend, completion time or guaranteed outcome.
What is the difference between this and the roll odds calculator?
This planner suggests what to check for your next action. The roll odds calculator illustrates an independent, constant-probability model using readable printed rates; it does not predict account-specific outcomes.
What are the two sliders actually doing?
They place you on the progress map — the planet ladder zones and the rebirth bands we have observed — and the advice matches that position. They are not formulas and will not output a number to beat.
