Question about efficiency

[minethegap]

Hi all,

The more I mine the more I understand that it is an activity that needs loads of tips and knowledge to be fully mastered.

I write this topic because I've noticed something weird since many days on the doge pool where I'm currently mining.

Here is the case:

My hashrate is 2,5x/2,8x faster than an other miner in the pool.
My invalid percentage is 0.42% and his is 1.39%
But he still mines exactly half the shares I mine on each round.
It has been like that practically every round we did.

So with more invalid shares he gets a better efficiency shares/hash. How ? Is there other factors to be considered to improve efficiency ?

Thanks a lot for your answers.

The hashrates shown on the pool aren't necessarily the most accurate.
