Likely ID calculation

Looking at this entry


At the time I looked at it there were ten agreements with the binomial ID Motacilla alba and only the one suggestion of the trinomial Motacilla alba subsp. yarrellii

The trinomial is right for this one of course but given the number of agreements with the binomial (including one individual with as many bird reputation points [4] as the person posting the trinomial ID) I would have though the Likely ID should be showing as the binomial.

Have I misunderstood the system or is something a bit odd here?

Likely ID

Yes, as the person who added the second ID, I was surprised at how many others my ID was holding back. Of course, there can be a huge difference between the 4 star reputations: There are some on 4 stars who have made about 200 IDs and received about 1500 agreements. Others, like me, are around 1000 and 6000 respectively. That's the answer, presumably. It has reverted to the first ID, now, though.

You are right. The reputation

You are right. The reputation system uses the number of reputation points that someone has, not the number of icons. The icons are only a rough guide to some wide limits on the reputation point scale. The width of these limits also increases as you go up, so it is much easier to earn your first bird than your second, your second than your third and so on.

Do you think we ought to display the actual points in a profile, as well as the badges?

Points vs badges

Would make sense to me to display the actual points.

Do points rise indefinitely or do you stop accruing them at some maximum level.

I agree. We shall do that in

I agree. We shall do that in due course.

There is no limit to points, though you can only get 5 icons. There is the option after that to get a 'Knowledgeable' or even an 'Expert' badge, but at the moment that is not automatic.
