your "more inside" isn't quite what i expected. to answer that, i suspect you need to understand what how many targets are available and how much effort is required in each case. if there are "unlimited" targets then the approach that gets most response for a given amount of effort seems logical - and that might be the 1000/10 case (if it's the same amount of effort as the 10/1 case and delivers more responses). but if you are talking about scaling in terms of technical implementation that i suspect the answer is that it is more fun.
