I find myself a little bemused by this thread really.
I'm not trying to be a party pooper, but, for me, it goes against everything that reading means to me..........
What relationship the number of pages/books one reads has to the enjoyment/information/experiences to be gained from the pursuit of reading, is quite beyond me.
If I find a subject I want to find out more about, I may read 6 books over a couple of months - sometimes because they're really big (!) sometimes 'cos they cover complex issues, and need careful consideration.
On the other hand, I may hit on an author I click with, and I could race through 6 books in a couple of weeks (ie the George Martin 5, recently).
I can what is rather grandly described as speed-read if necessary, but I rarely use it if at all possible.
And I am not suggesting that my approach is any more "righteous" (!) than the target-led method.........
I suppose I look on my reading as a leisurely family meal (rather like memorable ones in France) or perhaps an Irish wake - where the end is relatively irrelevant, but the company and the getting there is all-important !
Of course, it may be a hang-over from childhood, when I was always told/nagged "don't rush your food, you never know where the next meals coming from."
(Not desperately logical, but it fooled me, I suppose.............
