Its about same time period with same gpu models and HUGE diffrences shouldnt happen. Unless you think about winminer or some other crap that steals half your hash power.
If it would be 10-15% i would say ok but this isnt reassuring. Will see when payment received tho. maybe it doesnt show right since you didnt say anything about that :p
1. Bitcoin and especially Altcoin price fluctuations can be huge within a single day. So again, no comparison can be made unless you mine concurrently with the software you want to compare at the exact same time period.
2. Payments are guaranteed. Stay assured that you will receive your mined bitcoins when you reach 0.0025
confirmed BTC
Also, please use the latest version of UberMiner which indicates more accurately the time remaining until your payout.
Let us know the results after a few days of mining!
