Yes, also to add to that OOF...
When using the 1a+b~G(force cancel), you also have to remind yourself that the other variant(a+b~G) is much easier than using 1a+b~G, since you have to accurately input 1a+b~G to get the exact same results as normal a+b~G follow ups..it does make it a bit more difficult to do damage and combos with same effect..if you input the 1a+B~G too late(slow) even by the slightest delay, you miss out on the same damage you could inflict upon your opponent(s) that you normally could do with a+b~G and they will be blocking your free damage followed by it.. a+b~G is more lenient in that department.
I really wanna say that the 1a+b~G could be just frame input?.. i know the timing is more strict than the a+b~G.. because i can do a+b~G moves with my eyes closed and still get the follow up damage it offers ex:
= 6Bb~g~a+b~G,4b..just as an example, this is easier to do without the 1a+b~G inputs though(it can be done), you can still get the 4b after the very last force cancel from the example, BUT you cannot get the same results followed by it because it has very strict timing to it so you then miss even more free damage/wakes, so my advise here is to practice using your 1a+b~G until you get the hang(timing) of it, until then stick with normal a+b~G..which will then of course(after perfecting) save you more force meter(1a+b~G) but with a risk if you don't have the confidence in using it correctly
all in all ..don't frustrate yourself(s) with 1a+b~G too much..it takes a while to get the hang of it(timing is different than a+b~G) and in the process you could be tearing hair strands out..get used to A+B~G version 1st before learning to save force meter a bit with 1a+b. your still going to do the same amount of damage from a+b~G as you would 1a+b~g so don't worry so much about saving force meter, 1st learn how to control yourself from wasting your force meter before doing this version of the force cancel at all.
