In reply to Conquistador of the usless:
As I started the topic, I should wade in again. My point of view is pretty simple, but disjointed/rambling, as most of my thoughts are.
The info someone posts tells you the state of the route on the day, it is just one piece of information. You would need to be a bit dim to use this single piece of info alone & also assume that cos' the route was done three days before it is still in the same conditions.
As Michael G says the info can be applied to similar routes/aspects/elevations.
I live c250 miles from the highlands (perhaps I am a screaming Geoffrey or whatever you call them, tho I hope not), so I will take any info that is available. The only way I can assess conditions/best bets is remotely, I would like to have a good day out, I assume everyone goes out with the intention of doing a route (hopefully get to the top) rather than a 'hard fought journey'. Does it always need to be hard thought, perhaps sometimes enjoyable, bit of everything? A good day out can also be 'a hard fought journey' by the way.
The 'art of predicting...years of experience...patience' sounds a bit ludditesque (not a real word). Chill out, take it all in...get all the information...web...pub talk...years of experience...patience...whatever, all of them....why not?
It seems pretty easy to add a line when someone is updating their log book.
Perhaps I am wrong but I would suggest that most people have a route or a few routes in mind before they set off on the hill. Of course this should not be set in stone and reassessed once on the hill but the log books can help with the initial route choice.
As I said just information to be used as you wish. You are responsible for how you use it, if you have a good day out then good for you, if you don't then bad luck, depends how you use it.
What is 'outlaws are round'?
