Taxation (German tipster) not considered by software?

Hey there,

I am a German punter and currently getting acquaitend with the software “RebelBetting Lite”. Most bookies included in your software charge - in my case - a taxation on profit of 5 percent (e.g. bet365, interwetten, comeon) which I included in my settings. However, it seems that the software does not consider this when calculating the arbitrage. Do I miss something here?

Thank you for your support and congrats on your masterpiece software!
