While I love the idea of the chart showing synergy, I feel that if you start considering each fight, it can get needlessly complicated. Due to the 120+ champs and all the different ways in which they interact, with items and everything, I think that if we consider how good it is within a fight would theoretically give different results based on different champs...

For example, for anyone with natural sustain like Olaf, Irelia, Garen, etc, the efficiency of SV's passive effect would be more than that on a non-sustain champ such as Darius, Riven or Jax...

Or in another example, boots of mobility...given how their passive is worth 0 in battle (it's only present when OUT of combat), if you were to measure it's gold efficiency in a fight, it's worthless...but that by itself doesn't make the boots worthless themselves...

Another thing we'd have to consider is how well an item works on an enemy...especially tank-killer items like BOTRK or Liandrys...using their passive on an HP tank like Mundo would artifically inflate their value, while using those on a squishy like Ezreal or something might artificially deflate that value...

Because of all this, if considering effectiveness within a fight, we'd need to consider a baseline enemy or something, which would cause another problem of WHO the baseline is....the reason being that some passives/actives are only on monsters/minions (eg. jungle items of poacher and ranger, Banner of Command) so their effectiveness in a champion fight is less than effective...while others with champion based actives (Hextech Gunblade, BOTRK, etc) are worthless if we put them against something like a Super-Minion or something...

Finally, I think we'd have to consider it's synergistic effect across a full build, rather than just one item....for example, Iceborn Gauntlet is superb on Blue-build Ez, but isn't as great on regular Ez....thus, while it's effectiveness on Baseline Ez (without any OTHER item) could be measured, this effectiveness would fluctuate based on what other items he gets...

because of all of this, I feel that if we were to rate item gold efficiency or effectiveness, we might have to consider doing it as only item wise, and not as much on champ effectiveness in combat or something...there are WAY too many factors to consider in those cases...
