Comment (by cypher):

 Agreed on this. I suspect that one of the biggest barriers-to-adoption for
 potential users, in general, consists in having to manually tune
 configuration values (whose meanings are already arguably very opaque). N,
 K, and H are especially problematic in this regard since their appropriate
 values cannot be meaningfully determined without some prior knowledge of
 the size of the grid, ''however'', in a typical first-time use-case, the
 size of the grid is not typically known until ''after'' the user is
 already up and running and hits the WUI landing page for the first time (I
 say this on the grounds that first-time users are more likely to join a
 pre-existing grid to experiment with than they are to set up one of their
 own, given the time and knowledge commitments required of the latter).

 That said, a hypothetical first-time user would arguably experience less
 overall friction with N = 1, K = 1, and H = 1 (in which case, they face a
 low chance of a missing share, increasing over time) vs. N = 10, K = 3,
 and H = 7 (in which case, they face a high chance of a failed upload right
 away).
