Hi Tom

The worker dyno is *not* included in the $55, and there's no way to use delta 
indices with the Wooden plan.

I realise that means there's a *significant* jump in cost if you want to use 
deltas - I spent a lot of time working through the numbers to make sure the 
servers would be powerful enough at each level and the plans reasonably priced 
when I first got Flying Sphinx off the ground, but I just couldn't find a way 
to have the resources required for delta indexing at such a low price point.

An alternative, though, is to switch to real-time indices. They can be used 
with any plan level, the extra overhead from a Flying Sphinx perspective is 
minimal, and they *don't* require a worker dyno. The one catch is that Flying 
Sphinx does not back up real-time data, as backups are tied to processing of 
indices, and that doesn't apply with real-time indices. I do plan to fix this 
situation, it's just a bit complex, but I'll hopefully get to it soon. That 
said, crashes are reasonably infrequent (*touch wood*) on the Wooden plans, and 
almost non-existent on the higher plans.

... here's hoping I've not pushed my luck too far with the server gods...

To recap: deltas with a Wooden plan is sadly not possible (as much as I wish it 
could be) but real-time indices are definitely worth looking into.

Any further questions, do let me know.

Kind regards,
