How to use
Start with the most uncertain input

Save the assumptions and update them when measured data becomes available.
About this calculation
How is this calculated?
Total practice hours = daily minutes ÷ 60 × planned days × completion%.
What does this estimate exclude?
Equivalent workdays divide hours by the entered day length. Time accumulated does not establish learning quality, mastery or compound performance gains.
