I totally embrace this philosophy. Practically everything we suggest or advise is a guideline, not an absolute law of nature. The guidelines are there to try to help improve our odds, not guarantee anything. We just do the best we can.
I don't agree with this as the way to count the days, however. An egg does not have 24 hours worth of development 2 seconds or 8 hours and 2 seconds after it is put in the incubator. Intuitively it seems Day 1 should be the day you put it in the incubator, but that is not correct. It takes 24 hours for it to have a day's worth of development.
Suppose you put your eggs in today at 1:30 p.m. on Friday, April 22. If you candle them on Day 10, that would be on Monday, May 2. Lockdown would be on Tuesday, May 10. Hatch would be expected on Friday, May 13. An easy way to determine hatch day is that the day of the week you set them should be the day of the week they hatch, in this case, Friday.
A lot of different things can cause them to hatch early or late. One very common one is that if the incubator is runing a little warm, they can hatch a couple of days early. If it is running cool, they may be a little late. Heredity, how you store them before incubation, relative size of the eggs, and who knows what else can cause them to be off a bit.
It is not an exact science. Missing lockdown by several hours is not usually going to cause a problem. Komaki's method is normally close enough. But if you are trying to adjust your incubating temperature to get it about right, the target date you should be shooting for is 21 full days of develppment after you start them. I just think it is good practice to try to get it right.
Good luck on the hatch.
