I've been doing some testing to find out what number we need to "know" before the combination lock will unlock and it's only the 8 on the paint brush that we need to click on. Not sure if it's helpful but I noticed the WR is doing frog, apple and the paintbrush. Which is what I have done as well but I thought there must be a quicker way even if the clicks aren't that slow it's still clicks.

Not sure if it helps anyone but it seems faster?
