need help 256 block but bugged stats ?

Hi i was trying my 256 block all the night and at one jump i landed the block but stats was bugged and i have see no stats but when i looked the demo in slow motion it looks like 256, no duck at ground or something , i have send the demo to an friend on steam he have checked it with fps_death and he sayed programm says 252.x stats but you realy finished the block. i have make an lj pre not cj or something , is it why i make scroll duck + ctrl at landing and thats why it was buggy ?

pls can anyone help me and checked the demo what was it BUG? or what ever why i have finished the block with low stats ? wtf is it ?
