The True Minimum MaxMP?

Code:

case 8192: // MP
                            if (c.getPlayer().getHpApUsed() <= 0 || c.getPlayer().getMpApUsed() == 10000) {
                                return;
                            }
                            int maxmp = c.getPlayer().getMaxMp();
                            if (c.getPlayer().getJob().isA(MapleJob.BEGINNER)) {
                                maxmp -= 8;
                            } else if (c.getPlayer().getJob().isA(MapleJob.WARRIOR)) {
                                maxmp -= 4;
                            } else if (c.getPlayer().getJob().isA(MapleJob.MAGICIAN)) {
                                ISkill improvingMaxMP = SkillFactory.getSkill(2000001);
                                int improvingMaxMPLevel = c.getPlayer().getSkillLevel(improvingMaxMP);
                                maxmp -= 20;
                                if (improvingMaxMPLevel >= 1) {
                                    maxmp -= improvingMaxMP.getEffect(improvingMaxMPLevel).getY();
                                }
                            } else if (c.getPlayer().getJob().isA(MapleJob.BOWMAN)) {
                                maxmp -= 12;
                            } else if (c.getPlayer().getJob().isA(MapleJob.THIEF)) {
                                maxmp -= 12;
                            } else if (c.getPlayer().getJob().isA(MapleJob.PIRATE)) {
                                maxmp -= 16;
                            }
                            if (maxmp < ((c.getPlayer().getLevel() * 2) + 148)) {
                                return;
                            }
                            c.getPlayer().setMpApUsed(c.getPlayer().getMpApUsed() - 1);
                            c.getPlayer().setMp(maxmp);
                            c.getPlayer().setMaxMp(maxmp);
                            statupdate.add(new Pair<MapleStat, Integer>(MapleStat.MP, c.getPlayer().getMaxMp()));
                            statupdate.add(new Pair<MapleStat, Integer>(MapleStat.MAXMP, c.getPlayer().getMaxMp()));
                            break;
                        default:
                            c.getSession().write(MaplePacketCreator.updatePlayerStats(MaplePacketCreator.EMPTY_STATUPDATE, true));
                            return;
                    }

if (maxmp < ((c.getPlayer().getLevel() * 2) + 148)) {
return;
}

It would seem to me that this line of code dictates that the minimum MaxMP for every class is Level*2 + 148.

Pheelo's HP Washing Guide lists the Minimum MP Formulas as:

(This is for after 2nd job advancement)
Min MP Formula for Beginner = 10 x level + 2
Min MP Formula for Spearman class = 4 x level + 156
Min MP Formula for Fighter class = 4 x level + 56
Min MP Formula for Bowman = 14 x level + 148
Min MP Formula for Thief = 14 x level + 148
Min MP Formula for Pirate = 18 x level + 111

I am especially skeptical of the split between Fighter and Spearman/Page. No code supports this split for any job advancement or level up bonuses, or anything.

Does anyone have any data to support either the code or Pheelo's Guide? It's quite a difference. Or is there somewhere else in the code I should be looking for further minimums?
