RobboLito vs Rybka 3

some (experts?) are claiming that RobboLito is 'clone', (or a reversed-engineered version of Rybka 3) ... but, in reality RobboLito is very very different than Rybka 3:

- RobboLito recognizes many endgames and draws that Rybka does not

- RobboLito searches much deeper than Rybka 3 (reaches depth = 15 vs depth = 11 during 1/1 blitz games)

- RobboLito offers different analysis and PVs (principal variations) in almost every position tested

- RobboLito implements it's own unique and comprehensive tablebase (binary endgame lookup files) source code, included in the original (Linux) release is all source code needed to compile and build 1, 2, 3, 4, 5, and 6 man tablebases

- and it is widely being reported (from all over the world) that RobboLito is significantly stronger than Rybka 3
(at least 50 and sometimes more than 100 ELO stronger!)

question: how can reverse-engineering an executable result in a program that is so much stronger than the original?
answer: it can't...it's impossible

question: how can a reversed engineered 'clone' contain so much original and unique source code? for ex: see RobboLito's extensive and original RobboBase (tablebase) source code
answer: it can't, again, this too is impossible
clearly, the program authors are skilled programmers with a profound knowledge of chess engine development

question
: if RobboLito source code was obtained from the reverse engineering of another program, why does it not have pondering, multiPV, SMP, book support, or any UCI options or features?
answer: because it's a work in progress...in an early stage of development, and is not the result of the reverse engineering or 'cloning' of a finished and polished commercial product!

Robbo d2 x32 is simply trashing Rybka3 x32 one core 

404 games 1'+1'', AMD x64 Dual Core 4800+, 2G RAM, 64M hash, TB 3-4-5 on for Rybka, ponder off, book Chimera R3, Fritz 11 Gui, Windows XP32 SP3 

Robbo d2 - Rybka3 one core 
+239 =126 -39 

+188 Elo points for Robbo d2 
[169,200] one standard deviation 
[151,212] two standard deviations 

I tried to look at task manager, everything seems ok, Rybka is using the same amount of CPU load as Robbo. What the hell is the problem? Someone with an AMD Dual Core and Chimera R3 book can confirm my results? I think either the book is problematic for Rybka (a Playchess book with a lot of Najdorfs), or the AMD architecture. 

At least on my comp, Robbo d2 literally beats the crap out of everything (Robbos and Ippos not included).
