While there is an abundance of Level 4 regional groups, there is a considerably smaller number of Level 5 divisions. This is a result of the uneven number of teams in the various oblasts of the country. For example, While the Burgas Oblast can sustain four Level 5 OFGs that are funneled into one Level 4 OFG, clubs from Smolyan and Lovech are enough to form only one division at one level so these oblasts have no Level 5 OFGs. Still, some of the "provinces" such as Blagoevgrad have five Level 4 divisions, but no Level 5 oblast groups.
