Rival com points calculation

[stb]

Hi all!
Have one question. Anybody know how the Rival casinos
calculates comp points?
Recently I played at ClubVegasUSA and cashed in some money.
During playing I was able to calculate how much I wagered
by monitoring comp points progress. I don't remember
points / bets coefficient, but I knew how many points
I should to earn to clear the playthrough.
Now I'm playing at MayanFortune. Before start of playing
I bet $10 on a video slot and found that it corresponds to
10 comp points (if I'm not mistaken). My playthrough is $5000,
so I went to the cashier after reaching over 5000 points. But
found that I didn't met the wagering requirements. So I did
the test as before and it returned 16 points for $10. I repeated
the test several times and now $10 bet is 20 points.
Any ideas?

ClubVegasUSA is probably the only Rival casino which gives you 1 comp for every $ bet regardless of the games played. Others normally give you 2x or more for slot play. Slotocash gives 3 comps for every $ bet on slots and 2 comps for play on other games.

The 16 points for $10 of bets was possibly a mixture of table games and slots where you get 1:1 on table games and 2:1 on slots or vice versa. As for the 20 comps on $10 bet the calculations are easy.

Actually, you can contact live chat if you really what to know the conversion rates.

It seems I found the explanation.
Before I got different points due to free spins
and I forgot to take note of them.
