We reconsider the fine-tuning problem in SUSY models, motivated by the recent
observation of the relatively heavy Higgs boson and non-observation of the SUSY
particles at the LHC. Based on this thought, we demonstrate a focus point-like
behavior in a gaugino mediation model, and show that the fine-tuning is indeed
reduced to about 2 percent level if the ratio of the gluino mass to wino mass
is about 0.4 at the GUT scale. We show that such a mass ratio may arise
naturally in a product group unification model without the doublet-triplet
splitting problem. This fact suggests that the fine-tuning problem crucially
depends on the physics at the high energy scale.Comment: 13 pages, 4 figures; published versio
