TI helped me learn about things like balance, efficiency, drag reduction/streamlining, core rotation - all that kind of stuff that I knew nothing about. But if you feel like you already have good form, and now just want to add speed, you might not get much out of TI. But if you feel like you need to start with the basics, TI could be very helpful. Not much point trying to make an inefficient vessel go faster. At least that is the TI approach, as I understand it, and it makes a good bit of sense.
