Allow allowance to not be an "all or nothing" outcome to chores. If for example there is a daily chore and it only gets done 50% of the time that week, automate a matching 50% of allowance to get posted.
Preferably I would like to assign a given chore/task a % of over all allowance (because some things are just more important than others) and then if it is a task that repeats within one allowance cycle, a option toggle that makes it an [all or nothing] task or a [proportional] tasks. Setting it up this way would allow scaling up and down if over all allowance were to increase or decrease.
