Dominic,
Are you referring to the results of an assessment? (If so, you might wish to edit your question, so that more people understand what you mean!)
If so, do search in the Resources section for the title of the assessment, as there will be an article that explains the assessment in greater detail. For example, here's an article about the General Business Viability Assessment: http://www.venturenavigator.co.uk/content/general_business_viability_assessment.
The purpose of the assessments is to give you feedback to IMPROVE and ACCELERATE growth in your idea / business. If there are one or two areas that need attention, then very quickly, you could radically change your opportunities.
As you know, being "good" may not be good enough to succeed. That depends on so many factors. It's up to you to load the dice in your favour!
If I have misunderstood your question, please clarify and hopefully the VN community will be able to provide some insight!
