you havent sent me the file but from what you posted the % throttle goes up then down then up again to 99.6%
that doesnt tally with every other logging Ive done, so something is effecting your throttle position.
edit : I see vrsy has added it
are you sure you dropped to low enough rpm then WOT from say 1500 rpm ?
simplest explanantion is that you started the run too late and didnt bury and hold the throttle.
I'm not sure if traction control would drop the throttle % (so it may also be that) , I would also suggest logging your 4 cylinder ign delays just to be sure its all ok.
for whatever reason you car was not WOT until 3880 rpm......
