Sean K Reynolds has done a good breakdown of the ‘Take 20’ rule here: http://www.seankreynolds.com/rpgfiles/misc/take20.html

Imagine D&D would be a d100 system - you would need 100x the amount of time to take 100 ...argo said:I allow Take 20 on Craft checks so long as the player is willing to pay the mateirals cost 20 times.
Also note: a common misconception (or at least I encounter it a lot) is that Take 10 requires 10x the ammount of time as a single ckill check, it only requires the time needed to make one skill check. Take 20 does require twenty times the time because you actually are performing the action repeatedly.
