i wouldnt chunk, just personal preference.
look, i didnt think i was gonna get past dnb2
then i didnt think i was gonna get past dnb3
then i didnt think i was gonna get past dnb4
and now i am not sure i am gonna get past dnb5
i have no true idea how long it has taken me, but i wouldnt be
surprised if it was the equivalent of 5days a week, 20minutes a day,
for 365 days.
and here i am on dnb5, 2.5seconds, guaranteed match 0.1, interference
0.2
there are many techniques i tried, mostly increasing the trials,
increaseing the speed, lowering guaranteed match, increasing
interference, etc in order to get to the next level.
but i never did, nor ever will, chunk.
u can probly find numerous posts where i have given many details on my
techniques to get past levels, gleened from ppl here and my own trials
and tribulations.
u can even try just single nback audio or visual to break into the
next level--get comfy doing both singularly, then combine the two.
increase trials so u can start over in ur head without ending the
game--like 200 trials. when u lose place, just start over.
after u get good at that, then increase the speed by 0.1 to 0.2seconds
then lower the speed, increase interference from 0.125 to say 0.2, up
to 0.375--beyond this and i dont think it improves anything--it
actually seems to get easier, strangely.
and, the more days u play, lol, the higher u will advance.
may take 3months to go up a level.
