So, say that someone has 10% of the monthly sales of a competitor. Then the next month, he has 20% of the monthly sales of a competitor. Then the next month, it goes up to 30%. From month-to-month, it keeps going up until finally sales are up to 90% of its competitor, and they stay there.
All this time, the company has to keep his mouth shut, as no trend-watcher, investor or anyone else is going to be interested in these numbers until the company actually starts outselling the competitor, right?
Your problem, and that of many others, is that you are looking at the whole PSP vs DS issue with a preconceived notion of that it is all market domination. As long as the PSP isn't gaining on the DS in absolute units out there, it is not interesting, right?
But that's making the same kind of mistake as saying the GameCube lost the "console war battle" with the Xbox.
Well in my opinion the Gamecube did lost the battle against Xbox, however you could easily argue whether Nintendo lost to MS, on which I don't want to argue.
I personally found inefficients math to be interesting and meaningfull. The gap is not really that important, the percentage is more important. If you sell within 85% of your competition, then your marketshare continues to approach that number and when the install base is significantly large the gap between competitors loses it's meaning e.g 30million vs 10 million is huge difference, but 120m vs 100m is not.
