It's pretty easy to calculate how much effort it would take to remain in the 100% club for the Formula E release.

According to the table above, it takes 1,889 Gold to get 100% completion (assuming you had 100% completion before the release).

Let's assume each there is a new release every 6 weeks.

If you had 100% completion, you could probably make it into group B of the Weekly Time Trial every week, so that gives 600 Gold every release.

Watching 10 Gold ads per day gives 70 Gold every week for a total of 420 Gold per release.

Daily login bonus gives 220 Gold per month (assuming you are Elite). That is approximately 330 Gold every six weeks.

Combining these sources of Gold gives you 1,350 Gold per release.

That means you need 539 Gold to remain in the 100% completion club for the Formula E release. Divide 539 Gold by 6 weeks means you need to make around 13 Gold per day. That's around 30 - 45 minutes of farming per day.

Of course, this number changes drastically if you're not fast enough to get into group B of the WTTT, cannot watch ads or if you're not an Elite Racer.
