They are definitely two different issues, and definitely related. If there's any confusion, it's not on my part.
My point earlier was that we won't know if the P85Ds, once upgraded, are performing the best they ever will if they achieve just the small, currently promised improvements. lola and others are expecting Tesla to be under-promising and over-delivering when talking about just the .2 second improvement there. I'm saying that if the P85Ds, once upgraded, show only that .2 second improvement we won't know if "that's it", and that's all there will ever be, or if they may be in the same state we hope the P90Ds with Ludicrous are in now, which is waiting for an update that will improve their performance to a) fully meet their specs, and possibly b) meet the Motortrend testing which would meet and exceed the original P90D with Ludicrous specs.
lola had suggested it would be nice if Tesla let people know what was going on. I supported that. Others said Tesla shouldn't risk over-promising. I pointed out that at the moment, Tesla was still failing to meet the specs on delivered P90Ds with Ludicrous, so some explaining was in order.
That's how everything ties together.
Any explanation Tesla might provide for their current P90D with Ludicrous customers--an explanation which those customers are owed--would help us know what to make of the initial testing of the P85Ds upgraded to Ludicrous.
