That will increase as synchronization continues. firewall and antivirus settings may need to be adjusted. Mine has over 60 connections. Some people have over 100. Connections matter when your block is being solved at the same time as another. if theirs wins you get orphan block, if yours win they get the orphan.
Yeah, the wallet took longer than I felt was normal/average to start syncing but it is now up to 16 connections and about 10% done.
I found that calculator earlier; it looks like you need around 25k BEAN to find a block every month. Sure wish there was a calculator like this for TZC staking...
