Hi,

The new scoring system cannot distinguish between solutions which really 
attempt to solve hard subtask, and solutions which do not. The consequence is:

1) Points in scoreboard are not granular: for each problem, the points will be 
always either 0, or full points for that problem.
2) This makes us not able to estimate actual difficulty of hard subtask in each 
problem by looking at scoreboard.
3) This also makes us not able to estimate our final rank mid-contest.
4) Which makes watching scoreboard almost useless mid-contest.

The old system did not have the above problems because hard subtasks must be 
submitted separately. We were able to "bluff", however, by submitting random 
solution to hard subtasks, but with the cost of not being able to submit actual 
solution afterwards because we can only submit hard subtasks only once. That 
way, scoreboard was really exciting to watch back then, and we can estimate 
final rank, estimate hard difficulty, etc.

Any thoughts on this? Can we make separate submissions for hard subtasks, and 
make it submittable only once, like we had in the old system?

Thanks!
