Tuning is not needed for a lot of rubber for performance or extension of useful life.
I get HUNDREDS of hours out of Tibhar Aurus untuned, like 300+... and that rubber does every damn thing pretty damn well, but not the absolute best (ie T05/05FX gets 70% spin potential out of a 20% swing)
So I really have no need to tune to get some performance or extend the life.
Maybe way back when, in the early years of tuners, I would try it out to see what is what... all in all, it was too much work, time, and hassle/inconvenience to make it worth it.
You can get decent rubbers at low $30s to mid $30s USD a sheet if you buy 6-8 sheets at a time... so if you know what you want, it is pretty easy and you are not overspending.
I am talking about 3+ months out of a rubber even if you play it every damn day for hours... 6+ months for 10-15 hrs a week... we are talking about a $70 USD or less expense every 3-6 months...
C'Mon man, how Scrooge are U gunna be. That is pennies stuff.
Our sport seems to be filled with MILLIONAIRES who wear the same $3 white t-shirt (why is a damn TT player gunna wear a WHITE shirt with a white ball damn un-educated or insolent/indiffernt/don't give a damn about rules or ettiquette jokers)... and these richie rich jokas have the same 8 yr old rubber on their bat...
...and when they are asked to pay $40 a month for club membership that allows them play every day for hours a day... they cry a river to show how bad their character is.
These players WANT to play at a better level than the 50th percentile... but they too damn lazy, afraid, or cheepo to do what is needed to improve.
