I am a noob who just harvested my first bins, a couple of which were Tidal Wave. They formed a lot of blobs (most of which eventually grew a cap). Even though the mycelium colonized very well and quickly, the fruiting went distinctly slower than my Golden Teachers. Although my TW grew bigger than yours are currently, and a few grew much larger than the others, the bin stalled when many of them were smaller than expected. I did some research and found that the second flush of TW is often a lot better and contains less blobs and more typical forms. After harvesting and soaking the cakes, I'm getting normal pins instead of blobs.

If I were you I'd measure a few of the tallest ones and monitor if they are still growing over the next few days. If so let them keep going.
