Price Check for 6 Pups

Could anyone help me price check these pups?

1. Chert female base, 5 marks, 259 stats
2. Amber female, 6 marks, 260 stats
3. Saffron female, 7 marks, 267 stats
4. Birch female, 6 marks, 259 stats
5. Dinar male, 5 marks, 312 stats
6. Amber female, 8 marks, 308 stats

I use roughly this equation when pricing (of course take with a grain of salt, this is just how I personally have been able to sell a few more pups than I used to be able to when I went off my gut):
20+[(Regular Markings*5)+(RMA/Rare Markings*10)]*(Gender Mod)*(Coat Mod)*(Stat Mod)*(Skill Mod)
Gender mod being *.75 for males, *1 for females.
Coat mod being *.5 for T1, *1 for T2, and undecided yet for T3 as I don't expect to have one for a long while
Stat mod (currently, I'm thinking this will be shifting upwards soon) being *.5 if less than 200, *.75 for 200-300, *1 for 300-400, *1.25 for 400-500, and *1.5 for 500+
Skill mod doesn't apply when I'm pricing pups~

That gave me the following numbers:
1.  33.75 -> I would round this down to 25 or 20 
2. 20.625 -> I would round this down to 15 or 20
3. 45 -> I would round this down to 30 or 35
4. 20.625 -> I would round this down to 15 or 20
5. 37.5 -> I would round this down to 20 or 25
6. 30 -> I would round this down to 20 or 25

You have some lovely pups, I hope you're able to find some good homes for them!

Thank you! I tend to be awful at pricing in general and usually post when I've got pups I don't want since I can never figure out how much to do. This will definitely help make it easier to figure out what to price them around next time!
