This goal has the following fine print specified by sara4767:

In order to prevent accidental and/or intentional inflating of numbers and fudging of data, I must always time my practicing using the timer interface on the Beeminder iOS app on my phone. If I stop in the middle of practicing for an extended period of time (phone call, getting a drink of water, bathroom break), I must stop the timer temporarily until I start practicing again.
