Manager Walter Smith said: "The only problem I've got with the split is that we have been given three away games in a row.
"It's an impossible circumstance the League are in but it's strange that we have been given three away games when, to my knowledge, they have stated that would never happen to any club."
There have been a number of calls this season from managers in for the league to be expanded to include more clubs and Smith repeated his desire for an 18-club league on Tuesday.
And Bain pointed out that the present system leads to unfairness.
"Having played Dundee United twice at Tannadice, for example, in order to balance home and away fixtures, we are having to travel to Tannadice for a third time," he continued.
"There are a number of anomalies that the post-split fixtures have thrown up this season and this highlights the unsatisfactory situation that currently exists with a 12-team league and a split after 33 games - and outside influences seem to be becoming major factors in determining these.
"The SPL have said that the police did not want the final Old Firm game of the season to be decisive and therefore did not want it scheduled for fixture 34 or 35.
"They have also said that they did not want the game on the weekend of 1/2 May as this is a bank holiday weekend, but what difference does it make when the match is invariably played at 12.30pm?
"The other aspect is that Celtic are not being asked to go and play on the difficult surface at Fir Park when they have only played there once this season. Does that equate to sporting integrity?
"I think the time has come for a more considered debate on a better structure that removes the split completely."
