Exactly, and this is independent of skill level. In the past, anyone below 70 (i think) was able to collect a bod every hour. When the cache came out, they modified it to be the same, one every 6 hours, with the option to cache u to three bods. So, once every 18 hours, you can log on, collect 3 bods in smith and 3 in tailor. Hence my calculation of 6 every 18 hours.
