As the title saying, do you feel V15,16,17's gap between windows is more strange than V12,13,14's ?
V15,16,17's gap: https://i.imgur.com/kQKFTBO.jpg ; https://i.imgur.com/MpzSv4a.jpg . It looks a little chapped.
V12,13,14's gap: https://i.imgur.com/ypR1lEc.jpg ; https://i.imgur.com/xpLDpEc.jpg . It looks more uniform and seemless.
Do you have the same thought ?
