Well analyzed! Waka is actually 5-7 5-7-7 (the last 7 is optionally its own sense unit), but I didn't strictly follow the official Japanese syllable counts (techically, "Kampai" is KA-M-PA-I, "Yosei" is YO-O-SE-I, and "Yokai" is YO-O-KA-I), instead treating them the way their syllables sound to me, from my English native perspective, especially when they are spoken alongside English words and compared with how those words get their syllables counted. The way that "Kampai" actually gets said in practice nearly always sounds like KAM-PA-I to me, and so it works as a three syllable word for me, for the purposes of rhythmic poetry in English.

Good luck with your boast as well, I look forward to your weekly blogs!
