I send this ahead... Don't understand what I write wrong. I understand how it might come across in the wrong way. It is not meant in any nefarious way.
I did put it in quotes for that reason...
It is not a strict rule or "law" to do it this way!
However... The "formula" is the
conclusion (not vice versa) of many tests throughout the last 2 decades, hence based on "swarm experience" which ALL are based on practical tests, hence your statement only means that you try things for yourself (which is good) and don't care about the experience of others (which is bad)...
You make it seem that "YOUR practical experience" leads to the "only valid solution", which of course is your suggestion!
Perfection is impossible on a recordable disc! That can be achieved via mastered/"pressed" discs only...
I suppose you mean the result is "good".
Have you - at any place in time - actually scanned the result? Can you attach a result for some DVD-R here?
Just because a game starts or works, doesn't mean "it is perfect" (not even remotely)!
That does NOT qualify for a good burned result!
A disc with many correctable errors could work well and still stress a laser as much, that it dies much sooner than with an original disc!
I've seen the gradual degradation of multiple lasers from friends who did it "their way", like a KHS-400c - which is considered to be a pretty solid laser-assembly - by Verbatim Disc from Mitsubishi and the games loaded fine and it started getting worse after ~1 1/2 years... (maybe less)
It was even worse on the Slims... (faster dead laser)
It's definitely worth a try!
Not every writer supports it AFAIK!
I suppose the USB-Writer you have might not support that, possibly some laptop-writers don't either...
Also,... You can add laser-power to your experience.

Some writers barely get Verbatim golden at the same write-speed... with their underpowered diodes...
Especiallyllaptop-writers are MADE TO produce the best result at slower speeds than most desktop-drives which are more tuned towards higher speeds.
"burning" is a photo-chemical process (like old photos)! You enlight the reactive material too long or strong and you overexpose it... or too short or too less light and you underexpose it!
...hence OPC in IMGBurn or "Laserpower calibration" in CloneCD can make the result better.
Please do so, but rather add a disc-scan for C1/C2/PI/PO/PIE/PIF/Jitter!
"well written" and I am not saying that to monger about an error, but to point out that "perfectly written" is an oxymoron in itself, because written/"burned" discs are never perfect... It is inherently impossible with this kind of technology!
