[blml] Incomplete Swiss matches

[John Probst]

This is by way of consultation; as I'm involved.  My online site had a 
massive crash tonight, thus killing off a number of swiss matches in 
progress. We need to score them on an EBU 20-0 scale. The matches are of 18 
boards (and the scoring is Butler imps, although that's not relevant except 
that an award of 2 imps a board is appropriate if you're awarding average 
plus.)

We use EBU White Book for default regulation so if nine boards have been 
played the match is in good standing.

As I see it, this is a "no fault of your own" situation, but I dislike 
inflating VPs in a Swiss.

We could 1) score the number of boards actually played on an appropriate 
scale for that number of boards, thus avoiding VP inflation
2) Award average plus both sides and score as an 18 board match where the 
total VPs are > 20
3) Take a halfway house of some sort.

What do we do about matches that have played fewer than 9 boards? Our 
default VPs for a "no fault of your own" is 14. Can we adjust this based on 
such results as we have, and if so, how?  Taking the case where only 3 
boards or 8 boards have been played, it's unfair to adjust the VPs purely on 
scores attained, but something might be possible.

Await replies with interest.  John
