The best thing IMHO for getting camscores up is to have stuff on share that ppl can tip for while you're offline.
Vids is the number one thing that'll do this.
Having a sale on vids if you go on holiday or are camming longer hours than usual definitely helps.
At the end of the day, camscore goes up and down, it's good to be mindful of but anytime you want to grow your reach/income it will definitely dip as you'll be online extra and until those new people find you, it'll mean less per hour.
The most important thing is getting a good support foundation, once you have that and keep it...you'll be fine.
