IMP scoring method

[A2003]

The list of the scores played for 53 tables is at the bottom.

It conflicts with the imps awarded at the tournament.

Imp scoring is calculated from the difference and rounded in full Numbers

and awarded 1 through 24 using international match point scale table.

 

It is not clear what it is comparing to for the difference to calculate for international match point scale table. Why Fractions are awarded?

 

If I Play in section 3, is it comparing the score with section 1 Top score for the difference?

 

What is maximum imp you can get for one hand in this computer scoring method?

Each score is checked versus each of the others. Let's take your top score for example, +400. This score beat every other score. At matchpoints it would earn 52 MP (or perhaps if you award 2 points for each clear win and 1 for a tie, 104).. or 100%. I think you understand that part.

 

At imps, +400 is 100 points better than the six tables that earned +300. That would be 3 imps each per table (6x3= 18 imps). It is 200 better than those that were +200 (4 tables x 5 imps = 20 imps), it is 300 better than those plus 100 (12 tables x 7 imps = 84 imps), It is from +510 to +580 better than those that were -110 to -180 (15 x 11 = +165 imps), it was +600 better than the single fellow who was -200 (+12 imps), it was 1000 or 1030 points better than the 12 pairs minus 600 or 630 (12 tables x 14 imps = 168 imps), and it was 1200 points better than two pairs that were minus 800 (2 tables x 15 imps = 30 imps).

 

If you were then to total all the imps won by the pair that was +400, it would be +497 imps. To make this more normal looking, you divide by the total number of comparisons.. 497/(#tables-1) = 497/(53-1) = 497/52 = 9.56

 

To caculate the imps for all the other scores, do the same comparisons.

Inquiry beat me to it, but I did an Excel spreadsheet that proves all the figures for the table in the original post. I cannot find any way to upload a file, nor send it via a private message nor even via an email by clicking on the member's profile. Odd, that. No way to communicate it at all.

If I Play in section 3, is it comparing the score with section 1 Top score for the difference?

As the others said, your results are compared to every other table in the tournament, at the end of the tournament.

 

While a tournament is in progress, the IMP scores you see on the movie are computed using only the results from your section.

Have you tried using the clipboard?

Try to copy the spredsheet into Notepad,

via copy and paste, .... and then into

the text editor, again via copy and paste.

 

With kind regards
