Tao as a clear winner here. 
Some bigger rating improvements, number of total games in brackets:
Tao 5.4 2586 (520)
Tao 5.6 2652 (720) +66
Movei 00_8_163  2520 (680)
Movei 00_8_178  2558 (840) +38
Quark 2.05b 2538 (680)
Quark 2.35  2572 (1360) +34 
WildCat 2.79  2581 (600)
WildCat 3.0 2614 (1200) +33
Comet B67 2511 (600)
Comet B68 2541 (720) +30 
AnMon 5.30 also much improved over previous versions I would say although I only have games without Nunn positions for versions 5.21 and 5.22. Gothmog in the meantime improved with version 0.4.7 and selectivity 6 by 39 points after 520 games in gauntlets.
Again it could be seen that a lot of games are necessary. After 10 positions and 340 games Comet B68 and Ikarus would have been even much better and some others worse.
First results and games download for Nunn Top Tournament 2 with 18 engines including the newest releases and some betas will be available tomorrow when you visit my webpage.
