Use Single player settings difference

[Xandor]

I am looking a little at the difference between using Use single player settings and not.

Base stats (before manually adding levels) seems to almost not increase. Damage went from 396% to 436.6% on a tame I tested on but other stats was the same.

Looked at 2 megatheriums:
Without single player settings.
9372.8 health (base was ~6.7k before levels)
474.7% melee (base was ~408% before levels)
With single player settings.
12324.8 health
622.8% melee

Another megatherium that I put only points into health:
11668.7 health (base was ~6.7k before levels) turned into 17203.7 health.

Exp requirement is also lowered when using single player settings, this is both for player and tames. I went from lvl 91 not ready to level up to having 18 points to spend when I enabled use single player settings.
Tame went from 2 points available to 11 points.

Also I tried doing Broodmother on gamma difficulty with and without Use single player settings, it seems to be no difference (other than the additional stats you gain from leveling up tames).

Based on the stats it seems to be around 2x as much health per point and 2-2.5x as much damage per point with a slightly higher base damage.

I am unsure how it affects xp, harvesting, taming, breeding etc.
I tested breeding and I think time to breed again was ~5-8 times faster and the sped up egg hatching/growing made it so things grew up almost instantly so it is significantly sped up also but not sure how much.
