Significance of Delta in Bench Mark Scores

[dzjenkins]

Can anyone explain significance in minor change in Passmark Ratings. Example If I have a score of 4200 after running "all tests". How significant is a the delta in a score of 4000 or 3900? On the same computer or compared to another Computer score.
Thanx in advance for looking at this thread.

200 / 4000 = 5% difference.
