I've been observing lower European case numbers for a while now, specifically case numbers EU20### which do not interfere with U2 cases neither in 2014 nor in 2015 – these are representing the non-limited countries (other than U2).
Setting 2014 density at 100 points we had from December to March the following densities for 2015:
68.1 – 77.8 – 87.0 – 97.8
The filling of lower ranks is fast and parity almost reached. I did not follow the submission date discussion so can't say whether there is already a noticeable slowdown or not but I doubt there will be a low response rate for these countries (at the end). Responsible for the observed low response rate are the (indistinguishable) limited countries Ukraine and Uzbekistan.
Very interesting point. I'll take a look at that by country. Thanks DV4Roger!
