Gaps in Reiatsu

From what I understood (blame Jian if any of this is incorrect)

Every 50 Reiatsu would feel like double the power, and perhaps 50 vs 100 isn't exactly the best comparison since, well, that IS double.
Not sure about the details, but this'd mean a difference of 100 would feel like 4x their own power, and a difference of 150 like 8x.

I think this is OK, but this was with the old system in place. I think it's up to the people you thread with to decide what you will use.

EDIT: And while I was typing this it has all been clarified :') My bad

Vaporization will not be a major issue.

If you want to be in a combat thread with someone who has >300 reiatsu than you I can tell you from personal experience its possible to hit 300 reiatsu with a decent number of skills in 30 days or less.

If you want a thread that is not a combat thread you don't have to worry about it because they won't be flaring their reiatsu that much.

In the rare event that there is ever a prestige or post-prestige player who cannot control their spiritual pressure I'm fairly certain they will be the type who would cream you into the ground if their eyes met yours because that's basically reserved for a berserk-type character anyway.

And these are rules of thumb.

Meaning you will only be vaporized if you and your thread partner agree that's what you want to do.
