The orange numbers are the rate of growth for your qualifications. Each level is a whole (1.0) so growth of 0.1 will result in a new level in 10 days, growth of 0.05 will result in a new level in 20 days, etc.
The higher your qualification gets, the lower the growth becomes.
You can lessen the decline by continuing to expand. See the sticky thread titled "required qualification, help" in the FAQ section of the forum for some helpful guidelines to maximise growth.
Your actual qualification ratings are the numbers directly after the green bars which show the status of your current qualification level.
Green bar halfway to the end = halfway to the next level.
Green bar disappeared = just reached next level, etc |
