Carl, for me not one bit of yesterday’s s ride was “easy”, whether riding alone or in a large pack, taking my turn at the front, nor when I worked with 2 other riders for best part of a lap and especially not when I tried to bridge to riders in front. You may go faster when with others but you need the watts to be there and stay there in the first place. If you get dropped you then need MORE watts to get back. That may be your extra 100 Watts? And then easier?
Not to kick off an argument, which I seem to get into far top frequently on here at the moment, but I stand by my original comment. It is fairly easy to get PBs on Zwift (and I assume in real life too) when you're riding in a big group. We see this year on year in the TdF - the peleton moves at crazy speeds, the guys at the front working hard but those deep in the draft hardly pedaling.
Looking at my Strava most of my PBs were early in the ride when I was in a group of around 100 riders. I was towards the front of that group, so clearly working hard to stay in position, but for the effort I was putting out I was going way faster than I would on my own, or in a smaller group, and hence yes, it was fairly easy (relative to being on my own) to go fast and get a PB.
To get these speeds of 50 kph I was probably pushing 250 ish Bkool watts. When I was in a small group later on, with only 7 of us in that group, the same 250 watts was getting us only speeds of 40 kph. On my own to hit 40kph I was needing to hit 350 watts. Now, 250 is not easy, but 250 watts for 50 kph is easy compared to 350 to hit 40 kph
When I was on my own I was having to hit 350 bkool watts to bridge gaps. Once in a group, I could drop back down to 250 and 'cruise'.
Whilst in the groups I tried to stay towards the lead area as being dropped was painful. Every now and then my nose went in front of the pack then I would soft pedal until the pack caught me back up. I was actively trying not to be out front, but instead actively being selfish and just draft others

I wasn't in a team so didn't feel it was my job to help the larger teams
I accept that others with different trainers, or power metres, may have experienced the ride differently and I may not be the most experienced cyclist but I do know how 'hard' and 'easy' feel to me personally
