Take this analogy
Soldiers ... They do foot drill, weapons drill, Range practice, Weapon disassembly and reassembly, section attacks, company assault et al , battle camps etc......................
Now Those are all basics and forms (esp the foot dill, disassembly/reassembly section attacks) ie Kihon waza and Kata ................. they aren't called that but that is what they are now from them there is and has been analysis to obtain the techniques that are used to fight etc ie bunkai (ok bunkai is a bit wider possibly) and by learning the forms (kata) getting them down to a Tee and then the techs that lead from them (kihon waza) then they are analysed (bunkai) you then produce a fighting man/woman... and get verifiable results ........... make sense in those terms?
So saying anything that (MA) is Kata based etc and saying tey do not produce verifiable results is far from the case and in the Japanese context I would be fairly sure that the Koryu schools would argue fairly convincingly that the have produced results.
Maybe what is not being made clear is if when you are doing Kata or Kihon waza and you do not see where the application is or how then that is when instead of saying no it doesn't work or not that useless ....ask the teacher they will then be able to explain and show you
Also if you want to be effective and get verifiable results (as you put it) then first you learn the basic forms then the basic tech then you analyse and take from there. After all that is done then you learn the tweaks and the nuances and there by the full applications, you don't learn the shortcuts first.
It is very easy to look on you tube and see vids that in which it may not be readily recognizable as to what the end result is so be aware of that before jumping either on band wagons or to conclusions and also if you have not studied that art then bluntly how do you know, unless you are going on others opinions (now that opinion may be good or it may be flawed, as in they either did not like or bluntly couldn't do)
