Perhaps in the future having some tasks time locked and some allowed a set number of times each day without a time lock between completing is the way to go; that way people who are on limited time can still achieve points to reach at least bronze or silver tier. Also, the prior event (Spring Festivities 2018) went a week longer according to the wiki entry (don't remember on my own because it's been a couple years), and having an additional week is probably more help for most people compared to having 5 instead of 4 tasks (with how the points are allocated) because of people having different schedules.
