I'd give a rest day between, but try to have a single session where you _really_ stress yourself. Doing one and two here and there is fine but you should be doing more.
My friend had a pullup bar and when I stayed at her place (out the country, no gym I could use) I'd do as many pullups as I could until I physically couldn't do anymore. And a few sets of those too. Even the next day I could still feel a bit of soreness, which is probably a good sign. I've no doubt if you keep doing them regularly in this way you would eventually see good improvements.
Just doing them all the time / every day or adhoc doesn't seem like a good plan to me. Unless you really stress the muscle its not going to grow, and if you are always stressing them to the max then they wont have time to recover (so again, no growth)
