I have a chin up board over the door to my kitchen. I would usually 2 to 3 sets of easy reps in the AM, 2-3 sets at teh gym around noon. In teh evening around dinner and after maybe 4-5 sets total.
Method a climbing friend suggestede was to pick a set number of reps soemthing more than 50 and just make sure you get all 50 in by the end of teh day. This sometimes meant doing 8 or more sets before bed. Each week you add 10 to the daily total.
week 1 50 per day
week 2 60 per day
week 3 70.......
