If the next bull run were to follow a pattern, it can be both big, or small.

We haven't had enough of the substantial bull runs to see if there is any pattern in how big or small they might come.

But if we were to take the bull runs that already happened into consideration and predict the upcoming one from a pattern, then it would still be not possible, because currently there are at least two possible ones.

The first being a progressive pattern, and the second being a repeating, alternating, or random pattern.

If it were a progressive pattern, then from what we have, the next bull run would be smaller than the last, which was smaller than the one before it. and if it keeps going on like this till the forceable future, bull runs will be nothing but tiny little stubs.

If it were a repeating, alternating, or random pattern, we can't tell what the next one might be as we haven't had enough to draw a pattern. But if we were to just take the previous ones, There was one Big, one smaller, so the next will be Bigger.

Now I need to clarify that patterns are nothing but something our brain likes to recognize, and they also have a fair chance of happening, but that does not make them any form of concrete predictions at all. (and this post kinda proves it)
