As Ingineer has told us, the 100% setting is really 93.6% of the total. That is why a new LEAF has 281 GIDs with a 100% charge.
Based on this belief, I would say TickTock's 80% charge ending at 183 means that he has 61% of his toal new battery capacity when he charges to 80%. When he charges to 100% (93.6%) he has 74.6% of new capacity. Both numbers are approximately 19% lower than what would be expected from a NEW LEAF battery.
ETA: This makes a little more sense if you figure an 80% charge is 232 GIDs. That equals 77.3% of full, not 80%. Now the ratios for TickTock's readings are correct: 61/77.3=74.6/93.6=79%
ETA2: If that 79% number is correct, he is close to the second bar, which is at 78.75% IIRC.
A charge set to 80% stops at 80% SoC (real SoC, not what Gidmeters report), whereas a "full" charge usually is stopped from 94-95% SoC. So the difference is only ~15% of the total pack capacity. A charge to true 100% SoC would give you about 24kWh, but the battery ECU is more interested in making the pack last long, (or at least attempting to, Sorry Phoenix!) so it never allows that truly "full" charge.
Packs that routinely see 80% charges are usually more out of balance, so the initial full charge is usually less than even 94% until it gets a chance to rebalance. This will also make a full-charge Gid reading artificially low. For those attempting to assess capacity with Gids, several full charges in a row may be needed to peak your Gids to the real level.
