Same as Fig. 5, but planets grow with a 4 times faster growth rate (top) or 4 times slower growth rate (bottom). For faster growth rates planets grow bigger, especially in the early stages of the disc evolution when the pebble isolation mass is still large. Additionally the fast growth also interior to the water ice line allows planets to reach large massesand migrate inwards even before they are swept by the water ice line. Slow growth shows exactly the opposite behaviour, namely that planets stay small and that they will not migrate significantly before they are swept by the water ice line.
