I don't use a "secondary" for any of my ales (which is all I'm brewing). I will rack to AGE on something like oak for x weeks. But that's not until fermentatikn has finished and the brew is ready for next steps.
I would advise against using a secondary except for those times when it really does make sense. To do it as something for everything, IMO, is not wise.
Also, the boogie-men that people aee afraid of (that effect big breweries) simlly don't exist on the homebrew scale. I also get super clear brews without racking to secondary. I do use highly flocculating yeast (or better) so it settles into a nice cake in the fermenter.
For time frame, ignore the amount listed on instructions. Let the yeast have the amount of time needed to do what it can. Also, just because it's done fermenting does NOT mean its ready for bottle/keg. With fermenting as warm/hot as you are/did you'll probably need to give it more time to remove off flavors or get it to mellow.the manufacturers of yeast list a temperature range fkr a reason. If you're not able to chill the wort that far before pitching setup either a swamp cooler or make a fermentation chamber to reduce its temp and stabilize it. You'll get far better brew, far faster with good/better temperature control.
