No you missed the point again!

7. If the above mentioned procedure is used directly in the first day the Isha/Fajr disappears, then there will be a big difference in time between Isha/Fajr prayer time of the last day the actual Isha/Fajr prayer time exists and between the first day the alternative Isha/Fajr prayer time is used. Thus this procedure is not used directly when the Isha/Fajr time disappears! Instead, at the beginning of the disappearance period, the alternative Isha time is found by subtracting 5 minutes from the previous day (and 5 minutes are added to the Fajr prayer time of the previous day). This 5-minute increment is used until there is no gap found using the Local Relative Estimation method. Same procedure is used at the end of the disappearance period. Read the above again and you will see that they avoid the jump by starting the phasing process before the last day that 18 degrees occurs! Keep reading it, until it makes sense to you! I am not trying to pull the wool over your eyes and I am not lying!
