For starters, the RG score should be lowered for those responders who increase their number of answers with useless responses such as "definitely", "I agree", "thank you", "I follow", and the like. Such answers contribute nothing to the discussion and good answers often get overlooked because of the clutter produced by such answers. I hope that that is the reason for the lowering of RG scores. If so, I applaud 👏 .
Well, mine did by one point even though my recommendations and reads went up. This has happened before and its hard to understand. This scoring really should be abolished. Nevertheless, I agree with Karl about penalising silly responses.
perhaps you would like to visit Help centre and see under the 'Score' how can you improve or worsen your score. The RG score is calculated according to how your colleague see your work. As far as i know it is not simply an accumulation of numbers collected by your work. In some sense it would be nice to now more about the mechanism of RG score calculation, but in my experience this does not help much. In Slovenia, we have rather complicated system of numerical evaluation of research results. Anytime anyone makes this problematic, the reaction of authorities is not to reduce the complexity, but to increase it. The only sensible solution is to use numbers, like RG score, merely as a rough and not very precise indicator, and to focus more on researcher's actual publication. Quality over quantity...
I think there may be more than one reason for the decreased RG score. One reason may be the decreased interaction. The other may be because some of your followers might have un-followed you.
It is very much possible because of various factors. Basically, your RG score is a dynamic score which is derived through a black box algorithm that takes into account the overall contribution made by your research profile in that particular week. This algorithm, however, is not quite plain and simple to fathom. Only RG knows it fully.
RG score constitutes the reputation of your publications, your interactions with other researchers (in terms of Questions and Answers) and the number of followers. Now let me break it up for easy understanding. The contribution made by your publications can be termed as 'hard score' and it really don't decrease any significantly. But the other three derivatives of interactions between you and other researchers (i.e. Questions, Answers and Followers) contribute to what can be called as 'soft score'. This 'soft score' is what causes your RG score to drop/ fluctuate. Sometimes quite much significantly, depending on the intensity of your interactions in that week.
