I have some doubts about this.
Why reducing the number of bills on the floor?
And also... I have a lot of doubts about Article X. The tiebreaker is the VP and so I think you should explain that "If the VP is absent or the position is vacant...". But the 6 potential tiebreakers are Senators or simple citizens? It's strange that a Senator is the first tiebreaker because he is a "former Senator"...
Article X deals with seniority, not with breaking the tie at Senate votes. Tiebreaker here means that if two Senators start their term at the same day, these tiebreakers are used in that order to determine which Senator is considered more senior. For example, Windjammer and I both started our current, continuos Senate tenure in November 2014. However, as I had been already been a Senator once prior to that - in August and September 2014 - and this is of higher grade here than any of the offices Windjammer had held, I am considered officially more senior than Windjammer.
