Repetition
I know it depends on complexity and amount of data to be repeated,
You need to vocalize in those 3-4 but not the package of visual images(base , parts image and so on you get the idea)
1 day
1 hour 3 hour 6 hour –>

?
3 day
?
4 day

Question
What are the period in the 2 3 and 4 day that you should be repeating. 
after that its every 6 weeks
again it depends on amount and complexity, do you have to repeat every 6 weeks can it be exm. every 2 weeks (its usually very fast after 3-4 day with mental speech and drawing repetition takes only 1 hour) , does it introduce any kind of side effect if u repeat before that 6 weeks.Thank you for your time.
