VVV scoring system suggestion

This has been discussed a few times so I have come up with a system to suggest. The medals would stay but the current points would not.

Right now my system doesn't directly account for difficulty or map size, but mulipliers could be used for such. I wanted to get a base system out for discussion before working out all the minutea. The 10 point base is just a simple number I started with. Rounding to the first decimal just seemed easiest.

The system would be as follows:
Points are earned only if there are 2 or more entries. Each participant is 10 points, so if a setting has 4 entrants it has 40 points, 25 entrants would be 250, 2 entrants 20, etc.

These 3 tables are my example tables:
One Two and Three

So table one is worth 60 points, two is 90, three is 20.

For time based points:
First place gets the full value of the table, so 60, 90, and 20 respectively.
Take the fastest time and subract it from the total number of turns at the speed. For one this is 333, two is 260, three is 276.
This is the base used for point calculation. Use the same process for each entrant, and take the ratio of the number.

For instance on table 1 vexing would get 60 points. Moriarte would have get
