Is bus 616X to the city crowded by the time it reaches Muerants Lane?

I'm looking at buying a house in Glenwoord towards the norwest end of Muerants Lane. I understand bus 616X is the quickest bus to the city from near this area. However, as this bus has plenty of stops before it reached Glenwood (on the way to the city), is this usually very crowded? How was it in the pre-covid era? Also, are there direct buses to Mcquarie park?
