Alas, these are counterfactual results. Had an investor actually done this, he would have impacted pricing of the options, particularly as his position got larger and larger in such a way as to bascially nullify the results, particularly the period of significant outperformance late.

The problem is always that these returns aren't dollar weighted and the impact of success - which is that you outgrow the money that can be realistically deployed in nearly every strategy - is never factored in (how can it be, really).
