Basically that would mean that Goku's decision to find a way to effectively combine both speed and strength and to be able to master the SSJ form as if it were a base form were two seperate goals.
In any case, going by that definition, I don't think that neither Vegeta nor Trunks are FPSSJ since we see sign they are able to handle the SSJ form as easy as their base form.
Where is your proof of this? If they were using the graded forms in battle to make up for the difference in strength, because Goku and Gohan were still leagues stronger then them anyway, then it would be hard to tell if they had FPSSJ. Like I said in an earlier post the FPSSJ would also be effective in the graded forms because they would effectively be removing the power consumption from the regular SSJ form but they would still have the power consumption from the graded variation. If we were to make a formula for the energy consumption of the forms we can probably say it would look like this:
EC = SC + GC
Where EC = Energy consumption, SC = The default SSJ consumption and GC = the Graded consmption. Going by this forumula if we lay out SSJ and FPSSJ out next to each other we'd have something like this:
SSJ EC = 5,000 + 0 = 5,000
FPSSJ EC = 1,000 + 0 = 1,000
SSJ Grade 1 EC = 5,000 + 2,500 = 7,500
FPSSJ Grade 1 EC = 1,000 + 2,500 = 3,500
SSJ Grade 2 EC = 5,000 + 5,000 = 10,000
FPSSJ Grade 2 EC = 1,000 + 5,000 = 6,000
We can see here that the FPSSJ ability would also be very helpful to the graded forms so for Vegeta and Trunks who were lacking in strength, they could just use Grade 1 as the power consumption is still less than a SSJ who hasn't mastered the FPSSJ ability. Although it would be pretty easy to tell that they would still have trouble with the form because they would also be using the graded form on top of it. But anyway, while making sure there speed doesn't fall to a margin below their opponents a graded form would be a great deal of help with the addition of the FPSSJ ability.
