The Groundwork farming is killing my will to live bwos...I don't get how WitGod's guide is mathematically reasonable.

Getting a 3* Blue is hard enough alone, especially on a Groundwork parent where you're never going to get 1100 in a stat because you're trying to do as many G1 races and training all over the place for as many hints as possible. So that's forever a 5% chance to get a 3*(Plus the 20% RNG before that decides what stat it lands on).

Then the Groundwork spark itself is just a 20% chance to get it. Then there's ANOTHER layer of RNG with Skill White Sparks where it's only a 5% chance to get a 3* White Spark.

How the fuck is it mathematically feasible to get a 3* Blue Spark AND a 3* Groundwork White Spark unless the stars align.

Who is Mayano supposed to be breeding with in this chart?
