hm. I see.
well, I know you prefer to get the guide ready before the draftinfo, shows but then again, it's prety late now to change much anyway. ;)
So yes, it is adviseable to wait until the info shows and then colect info from teams.
To make sure you get it fully right I'd even try to find managers who didn't chance the amount for the entire season, so they are absolutely sure how much they invested, and how much info was free.
And I'd Also look if there's any difference between the prices.
I can help you for a whole season of 5000 scouting, I didn't change it the entire last season...
So if you find a few more people who invested either 0 or more then 5000 the entire season, you will get a prety good picture for your guide.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
