Something I realised about event tasks

Doing 100% of them every day is becoming a chore for me. Thinking about how the 50 token task takes literaly twice as long as the 30 token task, it's dawned on me that I can cut my playtime in half and still get 75% of the rewards:

Start day 1: complete 20 and 30 token tasks, which should bring you to over half of the 50 token task. Token total: 50

Day 2: complete 50 token task at the same time as the 20 and 30 token task. Token total: 150

From then on, you just continue doing this every day, collecting the 50 tokens every other day. At the end of the event, you will have collected 75% of all available tokens for 50% of the effort of doing all the tasks.
