One Click Mining Vertcoin Question

[troiano9]

Have only been mining for a few weeks.
have mined Bgold and VTC so far.
I am currently using One Click Miner and running a GTX 1080 ti and getting about 69 Mh/s.  I am on Network 2 that is less than 100 Mh/s
I understand that Vertcoin is a P2p pool so you get more payouts the longer you are on the same pool.  
After being on for a couple days i was getting .1 VTC every 1:45 but now it has gone down by half and im only getting .054 every 1:45.
Why the decrease?  Should i be tweaking any setting?  I am usually the top if not second best Hashrate in the pool and other people lower than me are getting a bigger predicted payout.
any help understand why would be appreciated.

Thanks

0.054 > 0.01. According to the profitability calculator with 69 MH/s you currently should receive ~0.03 VTC every hour on average, so 0.054 after 1 hour and 45 minutes sounds about right. It also varies according to the pool luck and the difficulty.

edited the original post.
I was making .1 and now only receiving .05.  What would cause my reward to go down by half?
Same hash rate, same pool but half the reward.  What am i missing?

My rejected hashrate is over 6%.  Is that why my share are lower?
