Not really. It really depends on BD's vision how each day react. Some days may have a lot of activities that need a few updates. BD break up the updates into number of pieces for the game's days. So, game 7 update was broken up to 7 minor updates to meet the full day. It take a lot of work and effort to do a full day with reasonable amount of details. If you look at the last update that seem really big, that was the whole evening update.
Again, I could be incorrect. However, I prefer to let BD or others to help answer that question. What I can say is that with the story and game, there will be number of updates for each game days. I like how BD do the background and detail information with this game. I am aware that with all the tasks that BD need to do is a lot of work to do for each game days. If BD planning to release update every two weeks, then it only looks like a fraction of the game day would be released.
Feel free to correct me if I am incorrect, however this is what I believe see based on the update and how the game flows. Remember BD does everything for this game on his own.
BD, keep up what you are doing. Looking forward for next few updated. I will check the game update at end of this month.
Have a great day...
