How many cave snakes does it take to level from 46 to 47?

I noticed it takes around 4 cave snakes to get 1% towards a level. This is an approximation because cave snakes are one of the monsters that can be worth more or less experience, the experience you get from them doesn't always remain consistent. Given 4 snakes it would take approximately 400 cave snake skills to reach 100% or level 47. Perhaps an hour and a half of playing given my stats.
