There's absolutely 0 reason to double clutch. That's for trans without synchros.One of the reasons I double clutch 99% of the time just old man driving around town.

only when its not running.I am going to start a “how often does you car go under 3500 RPMs” poll.
It shifts smoother, it gives longevity, and allows head room when you do beat on it. It's general good practice whether synchroed or not, especially the way slow low rpm shifts are in this mt82. It is very smooth/low effort, but to avoid the jerky clunky sort of thing while nursing it (around 1800 ish) double clutch solves it.There's absolutely 0 reason to double clutch.

It's completely un-necessary. You're actually working the clutch x2 as hard as necessary, including all the hydraulics and sundry mechanical parts.It shifts smoother, it gives longevity, and allows head room when you do beat on it.

Especially on a heel toe down shift, theres nothing wrong with giving everything the chance to spin at the same rate, without making the syncrhos work as hard.
I think you're misunderstanding my point. Worrying about the hydraulics getting worn faster seems like a bit of a misnomer, considering no one would worry about using their brake pedal too much in fear of wearing out the hydraulics.It's completely un-necessary.

There is no jerky/clunky shifting, ever, unless you don't do your part correctly. The clutch pedal isn't an on/off switch, it's a progressive, subtle, sophisticated tool.
Unless you are beating the crap out of your car, the clutch disc is most likely to go long before the synchros. Double clutching increases clutch wear.A synchro works like a brake, to match spin in the transmission, it is a WEARABLE part. I bought my car used with 57k on the clock, I have no idea how it was treated, how it was broken in etc. My part (and as you would do with an high performance car on a track) you baby whenever possible, so it doesnt break on you when you are beating on it. By double clutching at slow speeds you are lowering the work done by the synchros.
Is it necessary? Probably not a NEEDED technique, but it is a technique that will add longevity to wearable parts.
Agree.There isn't a specific RPM that gets shifted at. I don't drive staring at the tach. I use the acceleration and RPMs I need, at any given time. That varies with each and every singe driving situation.
Traffic and other considerations are what dictate what RPMs I shift at.
4.09's cure that7-8k going on highway on ramps, 5k max on streets, there isn't enough room to be able to go above that.
