I’ve heard greater numbers referenced before but I try to be generous when I don’t have the exact numbers at my fingertips. Due to your challenge, I did a little research to find a good source. You are correct... I was wrong...
According to World Christian Encyclopedia, there are over 33,000 denominations in 238 countries having increased in number from 8,196 in 1970.
I was not right or wrong about anything. I didn't make any assertion or claim. I just asked for the source of your statistic of 25,000 Protestant "factions".

Here you use the word, "denominations" instead of "factions". The 2001 edition of your source has it at 8,973 Protestant "denominations", not 25,000 or 33,000.
Also, according to your own source, included in that total of 33,000 "denominations" are Orthodox (781) and Roman Catholics (242)
Cordially,
