I have found that the maximum propensity to gain is to set your priorities right and then sit back and watch the river flow I don't mean that as a fishing analogy but more as a "let your ideas evolve in a organic way" So you would expect that you would achieve your top priority the soonest and lower priorities later How much you achieve is a rate issue and I don't think there are any fixed answers for that Obviously the are ways to accelerate your rate of progress through an analysis of the data and this is typically what the pundits vouch for But this a grey area. Since most start-ups are driven to grow revenues rate acceleration is very typical but that is a more a matter of business than engineering
