Well I use fridrich for anything other then 2-4 as I use Ortega roux and k4 and I switched to roux 3 days ago from my 16-17 second fridrich average I now average 19-22 and I don't care because I enjoy it, do whatever you enjoy don't get method superiority flamed and 5BLD you seem a nice guy we've talked on YouTube but you're one he'll of a roux fanboy, it has advantages and disadvantages like other methods so don't be a douche about it,
That's my metaphorical '2 cents' on this topic.
