it's okay to stay at soft cap since you won't need much resources unless you do frontlining. Anyways, the bucket count is always important.
the ships that needed BP are not much of a necessity unless you needed them under certain conditions. (but I will leave that to your discretion since this is where I should test on how well you manage your limited resources)
Just take it easy and level until there is no tomorrow. just remember to never stop collecting buckets.
