Slower ETH mining (Claymore / GTX 1070)

[SidETH]

I notice a difference in mining speed (not a difference in hashrate) the last couple of days. Previously my miner would mine 0.1 Ether every ±25 hours. Now it's gone up to every ±31 hours, but the hashrate remained the same. Any pointers to where I should look?

Claymore ETH miner
Windows 10
5x GTX 1070
Hashrate ±145 Mh/s

Here's my mine.bat file:

timeout /t 5
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ethdcrminer64.exe -epool eu1.ethermine.org:4444 -ewal WALLET.MINERNAME -epsw x -mode 1 -tt 68 -allpools 1
pause

Thanks!

Take a look to this chart https://www.coinwarz.com/network-hashrate-charts/ethereum-network-hashrate-chart and you will answer the question yourself

This is normal. Your cards are performing as they always have. The difficulty to mine ETH is increasing, therefore the same mining power mines less ETH other time. This will happen with all coins.

 Expect the difficulty to continue to increase with time to where you're making 0.1 ETH per month. This will take awhile but it will happen.

tldr; difficulty increased.

Wow I had no idea it would jump up in these large steps. I thought it would go gradually.
Will it (for example) stay at ±31 hours for 0.1 eth now for one month, and then jump again to ±36 hours for 0.1 eth?
