Is there a way to calculate the pet stats?

I wonder, is there a way to know how much the stats of a pet will grow up? A calculator would be awesome...

I'm pretty sure I saw a thread about stat growth before, but I can't find it.
I monitored some pets' stat growth in past but got tired of taking a note of all the stats for every level pretty fast. Stats like HP/def/m def seem constant, for example frog gains 30 HP per level (assuming it's constant all along). Those stats can probably be calculated quite accurately. However, not all of them grow constant. For example level 7 rhinodrakes physical resistance grows like this from level 22 to 26:
73, 74, 47, 99
I gave up after because I forgot to take a note at the next level, so I couldn't really make a conclusion. There might be a larger scale pattern.
Attack seem the least constant. This if for example a chart for attack over 5 levels, with the bottom green line being from shadou cub, top blue from walker and top red from tunnel digger.

Ecatomb has a list of calculated stats at level 105. There was a thread a while back to which I contributed data that helped him nail down a fairly accurate attack growth calculation.

The Ultimate Pet List has links to pages for select pets with their stat growth as far as I've followed them. (For some I have data from tame level up to level 100 or 101, with some gaps.)

Most stats have linear growth (the big and possibly only exception is attack, which has higher increases at higher levels.) I think Nariin has a mistranscription in her rhinodrake stats; pdef should increase 73, 74, 74, 73, 74, 74... (i.e., 73 1/3 per level.)

No one, as far as I know, has good data on regeneration growth, as it's a pain to measure and not all that important.
