Ever thought about taking the average of all the opponents for a player and dividing that by his/her rating? Then comparing the final score achieved, you get a sense of how hard the player had to "work" to get those points?

For example, in the Vic Open just completed, Zachary Loh had the following crosstable:

R1: Win against 1778
R2: Loss against 1886
R3: Win against 1699
R4: Loss against 1838
R5: Loss against 1669
R6: Win against 1524
R7: Loss against 1637
Average rating of competitors is 1719

Compared to Zach's rating of 1068, "difficulty factor" = 1719/1068 = 1.61 for a score of 3 out of 7.

What do you think?

R7: Loss against 1637
Average rating of competitors is 1719

Compared to Zach's rating of 1068, "difficulty factor" = 1719/1068 = 1.61 for a score of 3 out of 7.

What do you think?
I think your analysis is measuring something different from the C.I.

The 'difficulty factor' for Zach, and those in his RG, would always be greater than 1 (well, nearly always).
Zach got his up to 1.61 by having some good early wins, and this was commendable.
But, whatever the composition of the field, and the acceleration/divisionalisation/non-acceleration of the tourney structure, a good start would give a player a good 'difficulty metric'.

It is quite feasible some players enter a tournament with the objective of facing a high 'difficulty metric'. For example, there were players who entered the last week-end's NSW OPEN top division with ratings of 891, 1457 and 1498. Given that that there was a comcomitant event U1600 that they did not enter then clearly these players were chasing 'difficulty', not 'competitiveness'.
On the other side of the coin, in the same NSW event there were plenty in the U1600 who were not chasing the 'difficulty factor, and chose some other objective thus entering the U1600 instead of the OPEN.

The NSW events are better structured in my view to give competitiveness than the VIC events. That is, divisions are a better structure if most players want competitiveness.

Well done to Zach under tough opponents btw.

Thanks for the complement for Zach. I agree with your point regarding the NSW tournament. Not sure about NSW event being more competitive than Vic event. Might have to give that more thought with my Excel tool.

For a 7-round competition, there is definitely a case to be made for losing the first 2 rounds (or lose first round then draw second round), then show the "fist in the velvet glove"! Before the "Swiss system catches up", you would have caught up in the middle rounds. It depends on the competition and if there is an exceptional performer in the midst. Not that I'm condoning that sort of behaviour - that would not be ethical!

Default Difficulty over Competetiveness!

I think its incredibly exciting to play someone rated a lot higher than you!

Lets look it at this way;

If i was to play a person rated 1900+, i have a 2 in 3 chance of obtaining a good result (Win/Draw) and I get a good experience from playing such a person!

And besides, if one is to achieve a rating of 1900, the quickest way to get there is to score draws and wins against people rated much higher than you!

It's only logic

Isn't beating them (winning) the fastest way to get there?

Yes it is, maybe i could've worded it differently but i was generally speaking in the context of achieving a positive result against a higher rated opponent (Win or draw).

No need to get so specific either, i was just conveying a very logical point

Default You old Necromancer you.

There is a thread of the same title on chesschat.
It has been restored to active by this post.

I think I answered most issues raised in this new chesschat post, when I posted above, in this thread,
"The NSW events are better structured in my view to give competitiveness than the VIC events. That is, divisions are a better structure if most players want competitiveness."

The triple negative in the post
viz "If so does he disagree with the decision, reportedly of IA Bekker, to have no acceleration provision for a field size not more than 100?"
probably contains a useful question, but desperately requires a reword for the benefit of readers who cannot handle the Taswegian's word-gymnastics.

No, no - we mustn't associate Bonbot with the good people of Norway, that would be very unfair to them considering they have given us the most gifted young Grandmaster in decades.
