Firstly, it actually depends quality of the answers provided on the platform. The curators are more interested with answers of great quality as this will enable you to gain upvote from Musing.
The duration of upvotes or curation from Musing varies and sometimes takes time due to the effect caused on the voting weight or manna. The system will surely need some time to recover their voting power back. This explains why some people may end up with $0.99 upvote instead of $1. 00 upvote because the more musing curates or upvote people's posts, there maybe a slight decrease of upvote value or worth for other people.
In conclusion, don't feel depressed or uncomfortable with the delay in upvote. Your posts will surely be upvoted if it deserves to be upvoted even though it make take some little time.
Thanks for reading and I hope this helps.
