Need to be more careful in posts
When I posted 5-5 vs. 10s and As, those index numbers were for doubling, not splitting. I typed splitting there. That was wrong, and I offer my sincerest apologies.
When creating charts, and I always create a spreadsheet for myself to learn index plays for a new counting system (Omega Advanced II, Zen, Revere Point Count, Hi-Lo, etc.), I always include the same indexes for doubling down on a pair of 5s, using the same index number as a 2 card 10 ten hand against the dealer's upcards.
Hope that clarifies my prior inaccurate posting. I would go back and fix it, but not sure how to edit posts on this website.
