Hi, I'm the author of org-drill. I assume you are using the SM5 spaced 
repetition algorithm (default). The reason that the first interval is always
4 days is because this is specified in that algorithm. And the way that the 
learn-fraction is applied in that algorithm means that it can never have much 
of an effect on early intervals -- its effect becomes apparent later.

However, I have committed a change to org-drill.el which implements a new
variable, org-drill-sm5-initial-interval. Its default value is 4 but you can
change it to another value if you wish.

This change has been committed to the org-drill devel repository at:


You will need to download the file from there. I have not yet sent it to the
main org repo.
