Comparison between $\mathrm{\Delta }{\dot{\nu }}_{\mathrm{p}}$ and the waiting time (t^±) multiplied by the value of the second derivative of the frequency ($\ddot{\nu }$ before the glitch, $\ddot{\nu }+\mathrm{\Delta }{\ddot{\nu }}_{\mathrm{p}}$ after the glitch). The red points represent the glitches for which recoveries were detected, and the blue points represent the glitches for which we did not detect a recovery. The blue square represents a glitch for which we measured a positive value of $\mathrm{\Delta }{\dot{\nu }}_{\mathrm{p}}$. Top panel: Time (t⁻) since the previous glitch. The vertical arrows indicate the lower limits for glitches 1 (red arrow) and 46 (blue arrow). Bottom panel: Waiting time (t⁺) until the following glitch. The vertical arrow indicates the lower limit for glitch 45. As in Fig. 5, we included glitch 66 in this plot.
