I'd tweak your sentence as follows:

With the *istDS, the plain old TTL works very well, enough you can hardly 
find any difference.

the K10D. In A-mode this flash unit is working OK with the K10D, but
that is really a step down in technical progress and needs more

With a K10D you can use manual, auto or P-TTL. You will NEVER be able
to use TTL with a K10D, the camera does not support it.

OK, here's my suggestions:
1.  Perhaps the camera deliberately underexposes slightly with flash - 
keep it with +1 comp. and forget about it?
2.  A lens-specific problem.  With P-TTL, the pre-flash is at full 
aperture, and the strength of the main flash is calculated from this. 
If the lens stops down to say f/11 when it should be f/8, you'll get 
underexposure.  I've run into exactly this problem recently.  Test by 
comparing images in manual mode (no flash) with the same settings, but 
do 1 shot with the aperture set in-camera (i.e. lens on A), and another 
with the aperture set to the same nominal value using the lens aperture 
ring.  Exposures should be identical, so any difference means the 
aperture actuator (either on lens or body) is miscalibrated.
3.  P-TTL seems to use focus distance in its calculations, so perhaps 
close-up pictures using bounce flash cause the camera to throttle the 
flash output too much?  Again, mis-information from the lens re distance 
(is it a Pentax lens?) may be a cause.

Except that lack of TTL flash turns some of the not-so-old Pentax flashes 
(such as my 330 FTZ) into purely manual guns which are actually less useful 
than some of the really old guns (like the AF280T) which at least have an auto 
sensor in the gun.

The 330 FTZ gives good results in TTL mode on my DS so Pentax must have 
improved the situation since the release of the D.

Lack of TTL flash support in the newer DSLRs is going to be really annoying 
when I get around to upgrading.

I received my flash the other day and have been playing with it a bit
 indoors and out.

 First impressions are good, however the exposure results in P-TTL are a
 little disappointing.  I'm finding that for a shot indoors of my kids or
 similar at quite close range, bouncing off the white ceiling, I get spot 
 on
 results...but only when I've set the flash exposure compensation to +1.

 I would have thought that this flash (considering how damn expensive it 
 is)
 should provide proper exposure with everything set to default.  I know
 bouncing loses some light, but it's not a power problem as I can manually
 set the flash to light properly.

 Anyone have any suggestions?

I was finding the same thing when I did bounce flash with the camera in 
programmed exposure mode. A switch to manual exposure was the cure.
I don't mind, as that is how I usually use a flash, as I have a fairly low 
tech approach caused by many years of using simple auto flash units such as 
the Metz 60CT-2.
It is a little odd though, that flash accuracy seems to have regressed as 
the other technologies have improved.
BTW, it doesn't matter how expensive the flash is, it's still the camera 
that is controlling the exposure in any TTL method.

Preflash based TTL is inherently less accurate than TTL-OTF flash since 
the latter measures the light during the exposure. However preflash 
based systems are also fooled in less situations, so accuracy is to some 
extent a wash.

 Thanks for that reply mate.

 I find it annoying that it doesn't expose correctly in p-ttl and with the
 camera in auto mode.  Surely that is the basic requirement for them to get
 right?  Oh well, I'll just keep dialling in flash compensation or exposure
 compensation on the camera...at least it's easy enough to do.

I use the front wheel for exposure comp in programmed and auto exposure 
modes, and the back wheel for program shift in programmed exposure or for 
adjusting the aperture/shutter speed in automatic.

I would up your sensitivity. ISO 100 is slow for on
camera flash. I would start at 200 and go up from
there.

  Have you tried making sure that you're using the
 catch
  panel when bouncing off the ceiling? I've found
 that
  it works perfectly this way. It sends just enough
  diffused light directly toward the subject (and
 adds a
  nice catch light in the eyes). 
  
  I use it this way and have no need for
 compensation in
  P-TTL in AV mode with the K10D at ISO 200 and 400.
 My
  flash photos this way are as near perfect as I
 could
  want.

  I received my flash the other day and have been
  playing with it a bit 
  indoors and out.
  
  First impressions are good, however the exposure
  results in P-TTL are a 
  little disappointing.  I'm finding that for a
 shot
  indoors of my kids or 
  similar at quite close range, bouncing off the
 white
  ceiling, I get spot on 
  results...but only when I've set the flash
 exposure
  compensation to +1.
  
  I would have thought that this flash (considering
  how damn expensive it is) 
  should provide proper exposure with everything
 set
  to default.  I know 
  bouncing loses some light, but it's not a power
  problem as I can manually 
  set the flash to light properly.
  
  Anyone have any suggestions?
  
  Cheers
