Thanks for your comments. Yes, read your article and the mathematics is correct - I'd not considered it in that way as I myself do a lot of curation so find it useful to use the sliding scale and keep my effective power as high as i can.
So, in your opinion, is there a way of taking something like (13) and (14) forward so that they can seriously be discussed for possible implementation?
I am still looking at how to define the "success" of the overall platform so that any proposed new algorithms should, on average, improve that "success".
Thanks again.
