August + September 1 
East Record 5-4-4
At Home 4-1-1 (6 games)
On Road 1-3-3 (7 games)
Goal Differential +1
East Points 19
West Points 16

Season to Date – 97 Games
East Record 44-45-21
At Home 32-14-7 (53 games)
On Road 12-31-14 (57 games)
Goal Differential +3
East Points 153
West Points 156

This includes the September 1 games, which avoids breaking a week into separate months, and simplifies my record-keeping. The East had a mildly good month, winning 1 more than it lost in a month where the West had 1 extra home game. Overall, the West has 1 more win than the East, having played 4 more Home games, while the East has a +3 Goal Differential.
Looking ahead, I count 23 more games for 133 total. I believe this is correct, even though an odd number. If the 11 teams in the East played each of 12 West teams once that would be 132 games. It turns out Vancouver plays Montreal twice. What is further odd is that the East will finish with 68 home games to just 65 for the West. This is doubly odd because we know that NYCFC plays 7 Away to only 5 at Home against the West this year, so other East teams must play cumulatively 5 extra homes games to balance it out and make the numbers work. I presume all of this unbalance is done to offset existing unbalance due to have one more team in the West this year.

July 
East Record 6-12-5
At Home 5-2-2 (9 games)
On Road 1-10-3 (14 games)
Goal Differential -12
East Points 23
West Points 41

Season to Date – 97 Games
East Record 39-41-17
At Home 28-13-6 (47 games)
On Road 11-28-11 (50 games)
Goal Differential +2
East Points 134
West Points 140

The West takes the lead. They had a significant advantage in the number of games played at home in July and crushed the East in them. The East has a slight advantage in home games the rest of the way. Barring a sudden surge, it appears the conferences will finish very close to each other in head to head results.

June 
East Record 5-5-4
At Home 5-0-1
On Road 0-5-3
Goal Differential 0
East Points 16
West Points 18

Season to Date – 74 Games
East Record 33-29-12
At Home 23-11-4 (38 Games)
On Road 10-18-8 (36 Games)
Goal Differential +14
East Points 111
West Points 99

Things remain very tight. Neither conference lost a home game in June.

May 
East Record 7-8-5
At Home 5-5-0
On Road 2-3-5
Goal Differential +3
East Points 26
West Points 29

Season to Date – 60 Games
East Record 28-24-8
At Home 18-11-3
On Road 10-13-5
Goal Differential +14
East Points 92
West Points 80

Terrible month at Home for the East, which has 4 more wins than the West but has played 4 extra Home games. The race for overall interconference superiority looks like it will be close this year. The West is stronger than it was last year from the top through the middle of the table.

April 
East Record 10-7-1
At Home 7-3-1
On Road 3-4-0
Goal Differential +4
East Points 31
West Points 22

Season to Date – 40 Games
East Record 21-16-3
At Home 13-6-3
On Road 8-10-0
Goal Differential +11
East Points 66
West Points 51

The record is a bit misleading as the East has 5 more wins than losses, but also played 4 more Home than Away.

I’m keeping track again this year, but I’m not going to make weekly posts. I plan to do it monthly. If at any point you want a mid-month update for some reason, tag me and I’ll try to respond. As always, I use the MLS W-L-T format and all records are from the East POV.

Week 1 and Season to Date – 3 Games
East Record 1-2-0
At Home 0-0-0
On Road 1-2-0
Goal Differential -3
East Points 3
West Points 6

Next update should be first week of April to cover the full March results. NYC has the only East win, and Atlanta losing 4-0 to Houston killed the East goal differential, but it was worth it.
