I plan to respond just to replies regrading math and F400 algorithm, not to other comments.

As an example, assume you are a 2000 point player and play two games, one against a 1000 point player and one against a 3000 point player. If you beat the higher ranked and lose to the lower ranked player, you'll end up with you'll end up with a net loss of 10 points, or if you lose to the higher ranked and beat the lower ranked player, you'll have a net loss of 3 points. However, you went 50% against players with a mean ranking the same as yours, so your analysis would have suggested a net zero point change. In stock market terms, this is known as "draw down." Actual performance over an entire group will be less than expected based on the average of the group.
So from your example, you will get higher benefit (-3 points) if you lose to higher ranked than if you lose to lower ranked (-10 points). So, let's see in average who TOFU lost (and draw) vs, were them lower or higher ranked than TOFU? Lost sets were vs LOW (1099) and OSA (1139) while draw was vs TFFS (994) while average opponents' rank was 1006. So, following your logic, TOFU even got a profit in comparing with averaging opponent rank, because they lost points vs opponents who are the same like average (TFFS) or much stronger then average (OSA, LOW) which means they achieved wins vs clans lower ranked than average, which is with your logical explanation scenario which would give to TOFU more points than what they would get in comparing with average clans' rank. As conclusion, if my previous consideration lead to result that no points were gained nor lost in RL3, then with your new input conclusion is that TOFU even gained some points from RL3.

Just to answer Josko's Pt.1
1. When KORT (ranked 1393) lost vs TOFU (ranked 1357) by only 2 games 29-31 then KORT have lost 44 points.
Conclusion: losing by so small margin of only 2 games from clan who is 36 points lower ranked costed 44 points.
Your conclusion is wrong. During the period 1-15 May 2013 for which IcePack did the F400 there were other considerations to be made.
1. KORT had results other than the 29-31 loss to TOFU, so you cannot say the TOFU result cost 44pts
2. KORT will have lost points due to ageing of the May 6th 2011 win over THOTA
3. TOFU during 1-15th May 2013 recorded wins of 31-29, 14-2, 9-3, 12-4, 7-5 & 10-2....yet our points increase was a lot less than the 44 that KORT lost, so it is quite clear the singular TOFU-KORT result did not cost your clan 44pts.
So get your facts straight Einstein before you go accusing people of being a liar.
In the same ranking update, TOFU got 36 points and KORT lost 44, so point value gained/lost from that war is somewhere around that numbers, in my consideration it is irrelevant is it 36,37,40 or 44, those numbers are all in the same range anyway.
As for your "advice" about getting facts straight before accusing people to be liar, the KORT-THOTA war were included in ranking with date KORT z-THOTA 33 27 04/19/11, which means that on May 1st ranking that result was already aged and does not have influence on May15th ranking. I think I do not see the first time that you are pointing fingers at me for telling untrue facts, while actually you are the one who speaks untrue facts my friend
Looking at only KORT's results from May 1st to May 15th, there were the match vs TOFU, and 13v3 win vs DB, which is value around 1350 ranking, so that one result did not have big influence to our rankings. That said, KORT's net loss of points is more similar to real net gain/loss of points in that war than TOFU's net points won, because TOFU had 5 other mini wars in addition to the big war while KORT had only 1 mini war included together.
As a conclusion, no matter how much you try to go around facts, the net point loss was around 44, because weight of that challenge was 61 while weight of other included war was only 16 and result in the other war was not out of average for given clan ranks of KORT and DB.
Anyway, of the whole my initial post the most analysis was written in point 3, which for sure is the most important point, so here I will quote the most important conclusion which considers RL3 results only:
josko.ri wrote:For comparison and concluding how many points this can cost TOFU or get to TOFU, I was searching for another match of similar ranking opponents and similar final result. I found IA (1263) vs LEG (922) [341 point difference] which ended 28-13[68,3%] from July 2013 ranking as a fair comparison to TOFU (1375) vs average RL opponents (1006) [369 point difference] which ended 93-51[64,6%]. Point difference between IA and LEG was little lower, but total score was little higher so ranking points awarded should be more or less equal. IA neither won neither lost points for winning that challenge because they had 1263 points both in July 15th and August 1st 2013, and the result was included in ranking at July 29th.
Conclusion: If IA which is very similar case did not lost nor get any points in war of 41 games, then also TOFU for similar winning and ranking difference conditions should stay more on less on the same number of points like they would have if they did not play RL. Weight of the challenge in this consideration can be neglected because IA had 1263 from their 380 games in last 2 years, and to that was added win of 28v13 which obviously had point value of around 1263 and weight of 44 games, so if weight was higher it would still be the same in averaging with their previous score.
