This Idol Only Has 3 Seconds of Comeback Lines?

Recently, TWICE made their first ever summer comeback with the song "Dance The Night Away'. However, some fans are quite not happy with the line distribution for this song. Let's take a look at the table below.

Without considering the 'all together' parts of the song, Jihyo has 29 seconds of lines, Nayeon and Mina around 22 seconds, meanwhile, Sana, Jeongyeon, and Tzuyu have approximately 15 seconds. However, Momo and Dahyun have only 9 seconds and 7 seconds of lines respectively. What is even more unbelievable is that Chaeyoung only has 3 seconds of lines!

What's your thought on this matter?
