This isn't my field of expertise but I had some education on the topic years ago. I could see 102%, maybe 105%, but 231%? Nope. Not for more than a very short time.

relative humidity is by definition a percentage of capability. How much moisture is the atmosphere capable of retaining under given temperature, barometric pressure, etc.
In other words it's a scale of zero to 100. It's actually more complicated that that but that's an easy way to remember it.

Having said that, it is possible uncer certain conditions to go over 100% but that capability is projected or estimated. It isn't perfectly accurate under all conditions. If the air cools quickly it might take time for the moisture to condense so for that time it would be over 100% but not much.
