VP scales in Swiss Pairs
We run a local Pairs League (a round robin) using EBUScoreSwissPairs, and there are four tables in each division and each pair scores up the 10-board match with the three pairs from the other tables sitting in the other direction. We convert the resultant total imp score to VPs. We use the "cross imps divided by sqrt(rc/2)" option as this (imho) represents the fairest calculation.
We are seeing anomalies in the calculation of the VPs done by the scoring program. We have examples of
* score is 26.1 imps converted to 18-2 while the tables (WBF-D as displayed at setup) says that 17-3 goes with 23-27 imps,
* score is 0.4 imps converted to 11-9 while the tables says that 11-9 goes with 1-3 imps so we expect 10-10,
and about 5 others that could be attributed to rounding errors but still look wrong.
It could be all about rounding errors, or it could be that the two parts of the program are working on different old/new VP scales.
It is not a great problem but it would avoid having to explain to people why scores don't match what they expect if we made these consistent.
