etime

Etime is the estimated amount of time each player would use if they made 40
moves in a given time control.

FORMULA
-------

The formula for determining etime is:

 o etime = (time + inc*2/3)

'time' and 'inc' refer to the standard 'time' and 'inc' settings used in
"match" and "seek".

CATEGORY
--------

The delineation between lightning, blitz, and standard is based on etime.

Lightning: Etime is less than 3 minutes
Blitz:     Etime is between 3 minutes and 15 minutes
Standard:  Etime is 15 minutes or more

EXAMPLES
--------

Because of how the formula works, it's easiest to find the adjustment based
on the 'inc'. Then you just add this to 'time' to determine your etime.

0:  Etime: +0.0
1:  Etime: +0.6
2:  Etime: +1.3
3:  Etime: +2.0
4:  Etime: +2.6
5:  Etime: +3.3
6:  Etime: +4.0
7:  Etime: +4.6
8:  Etime: +5.3
9:  Etime: +6.0
10: Etime: +6.6
11: Etime: +7.3
12: Etime: +8.0
13: Etime: +8.6
14: Etime: +9.3
15: Etime: +10.0

In this way, we can easily see that a '2 12' blitz game (the most common on
fics) is 2 +8.0, or 10 minutes. Remember that etime is per side, so the total
game time would be twice that.
