Usually a deadline can be a default of the pool as it is in the qbundle wallet.
It can be changed ...but the best way that I know is to increase the plot sizes (HDD) And it will be just fine.
If you do that you can see day by day that your shares will grow .
Or...if it is too much stress...at the current moment you can sell on Ebay the HDD and then you can just buy some burst ..like this you have a lot more coins that just if you would mine them.
Any step in my view will be a good step...and remember if you are not sure ...just do what is best for you.
