I don't know why mempool.space allows the mempool to spill over 300MB, but mempool on my node is 300 MB since that is my limit.

Yes, 300 MB is the default value, but you can set it higher if you want. Would be nice to know what their actual limit is

I do 500MB and mine is only showing 478MB total. Not even full yet
