It is Mbps - it was likely only momentarily using that much
AIUI the meanings are
Recs – records stored - whether relevant or not
Peers – as it says, the other nodes your nodes know about and are talking to
Conns – connections - all the other nodes your nodes know about
Screenshots should not be a problem - just use your snipping tool (Is that still a Windows thing?) or other desktop screenshot tool and paste in directly with Ctrl-V

Recs
There are two types of values that recs could be.
records being held in records_store directory that the node could retrieve if asked.
records the node is responsible to hold, these are records that the node is one of the closest 5 nodes to (XOR address space)
If recs is around 20-50 at the moment then its probably the responsible records. If in many hundreds to thousands then its all records held.
Peers
Previously this was an instantaneous figure which really was connections. But now that connections (conns) is a figure being shown then ‘Peers’ should be the routing table peers and the ones the node will maintain a connection to. Typically around the 200 mark and fairly steady changing only by a few.
Conns
Just the number of connections the node has at the moment of status. This can vary from a hundred or so to thousands at any particular time.
