Exactly. All Saiyans learn new techniques through varying degrees of BS, Goku learnt the Kamehameha before knowing what ki was, Vegeta learnt to hide and sense power levels by simply knowing it was possible, Goten and Trunks became SSJ barely even knowing what SSJ was and Gotenks got to SSJ3 before SSJ2 by seeing it once.
U6 Saiyans power upgrades seem positively mediocre in comparison.

Really Shouldn't, to quote Vegeta after young Trunks went Super Saiyan "Naturally, it's a Super Saiyan Bargain Sale"
