// TODO Probably the description ^ is not too correct, this method actually takes 1 value each for the last 50 years,
// then the X last months, where X is the month we're in (september = 8 starting from 0)
// and all the days in this month
// Allowing for multiple values in a single day for habits we probably want something different:
// For free users:
// - At max 30 values for today (max 30)
// - 1 value each for the previous 61 days (2 months)
// - 1 value each for the previous 10 months (max 10)
// - 1 value each for the previous 50 years
// - Total: 30+61+10+ a few years ~= 105
//
// For subscribed users
// - At max 30 values for today (max 30)
// - 1 value each for the previous 364 days (max 364)
// - 1 value each for the previous 12 months (max 12)
// - 1 value each for the previous 50 years
// - Total: 30+364+12+ a few years ~= 410
