Is there a good heuristic value for choosing the right value of t so that the bezier curve reacts to changes in b1? Like for example, t could be a sensitivity coefficient. If t is large, the interpolated points will shift more towards the control point (b1). Is there an algorithm to adjust this in creating bezier surfaces, or do we just use 0.5?

From my undestanding, each value t corresponds to a point on the final Bézier curve so all values in (0, 1) would be used to create a single curve.
Re: your example - as t increases, the first interpolated point will indeed shift toward b1 but the second one will shift away from b1, so that simply creates a point further along the resulting curve.
