Who tweaks VTF too?

I can't say why it took many years for me to suddenly arrive at this point -- although I can identify the precipitating occurance as actually being mistake I made (as I suppose is often the case with many discoveries, large and small) -- but I've recently opened my ears to the practice of tweaking VTF for each record played, to very worthwhile effect. Generally within a range of up to about +.15 above the upper limit of the cartridge manufacturer's recommended setting of 1.35g-1.5g for my medium-compliance, line-contact MC cart -- i.e., up to 1.65g or anywhere in between, depending on the record being played, in about .025g increments.

Tracking a bit heavier accentuates the lower frequencies and tames the higher ones, for records that could use more weight or solidity and/or a reduction in gleam or glare or airy-fairyness, while tracking lighter does the opposite for records that sound overly thick or could use some opening-up (within the bounds of maintaining good groovewall contact, of course -- I never even run in the bottom half of the recommended range, much less below it). This minor revelation has helped significantly to increase my listening satisfaction with records I formerly would've just chalked-up as being slightly but irretrievably problematic, whether that problem might have been a subtly annoying touch of glassiness or peakiness or lightness in the loafers.

Each recording seems to have its own sweet spot balancing control, tonality, timbre and texture (within my system context), and after doing this individual fine-tuning procedure for a few weeks I've now started to intuit appropriate setting adjustments as needed, based on a record's initial sound and my growing experience with the outcomes. So I've definitely crossed over the proverbial Rubicon regarding tracking force and no longer regard the recommended range as inviolable, or VTF generally as a set-and-forget, one-size-fits-all proposition whose 'correct' value is predetermined, to be temporarily increased only in the event that dynamic-trackability difficulties are encountered. It's another thing to be tweaked! But also one of the easiest and quickest to do (at least with my tonearm -- I guess with some others maybe not so much). Anybody out there with me on this?
Update: 800 page views now, but still no affirmative responses that anyone else tweaks VTF to suit individual records.
Hello Zaikesman,
After following this post I will give it a try. If it can make an improvement I'm all for it.
Do you find that it is by individual albums or by the lable, such as all EMI's are set one way and RCA's another?
I assume you keep a list of the settings. Sorry I have not read all the post's yet, so if you have already answered the question I apologize.
I'm glad that you have taken the time to get the most out of your record play back system. Thanks for sharing this tweak, it never occured to me.
I usally set the VTF on the HI side of the recommended setting and I will adjust the VTA as required.
I'm trying to listen to nothing but albums lately, so this would be the time to do some tweaking.

Gosh no Joe, I'm nowhere near organized enough for that, I just go by ear for any particular record on any particular day. But since I assume some of this has to do with room temperature, which varies (and presumably little to do with such potentially label-specific attributes as vinyl thickness), I think that's the way it's probably gotta be. Please let us know what you find...
Some of us have been doing this for a long time, and I know some who record this information for each LP. I thought you understood that. I keep o-rings to add to the arm stub of my Triplanar and my Talea has finite tracking force adjustment. However, it has not been my experience that focusing on only one parameter solves every situation.

Temp and relative humidity do play a role in how much gross VTF is needed.
