Off the top of my head I believe you'll be in the 700-800 range. Certainly longer than the rechargeable battery, which doesn't have as high of a capacity as the one used in the K-3 series.

I used to get over 1K with my K100d, this was with minimal flash and "chimping"

As above. Loads and loads. 2x the rechargeable at least.

If "in theory" is to be believed, my rechargable AA batteries offer 2000mAh each, and the Wasabi battery is 2300mAh. So about 3.5x there...

But the Wasabi is at the full voltage and the Li109 (K50 battery not K3) is listed as 1400mAh not 2300mAh and in practice it actually lasts a bit less than the 1050mAh original Pentax battery which leads me to rate it at about 900mAh. I think the more important point is that the AA's are drawn down collectively (in series for voltage) which means the total capacity is equal to the capacity of a single battery (2000mAh or 2200mAh depending on the AA's you have). Essentially a set of AA's has close to 2x the mAh of the Li-Ion OEM battery and slightly more than 2x the Wasabi from practical experience. But the Lithium non-rechargeable AA's are even stronger (3000 mAh or so) and they are less sensitive to drain rate. Ni-Mh AA's drained too quickly (by lots of live view) will have only around 1000mAh capacity.
