Predicting the time to mine a block

[feofhweufheuiwhfef]

Is there any way to predict the time to mine a block?

On Ghash.io, I've seen blocks mined in a few seconds, a few minutes, up to as long as around 2 hours.

This seems highly unpredictable, but is there any way to predict it whatsoever.

I was thinking about going through 1000s of blocks, and seeing how the average block time changes over time, e.g. what is the average for the last 10, 100, 1000 blocks, and if at any point the average becomes in the same, in which case it would be predictable.

But I haven't done that yet.

So, does anyone know if it's predictable, and if so, what is the average block mine time?

The bitcoin network is supposed to adjust the difficulty to make a block to be mined every 10 minutes.

so you mean there's no way too predict the time to mine a block.

I suppose you could average the time used to mine, but it should give you something around 10 minutes per block anyway.
