Bet ramp confusion in blackjack attacks worlds greatest simulation

In blackjack attack I belive the worlds greatest simulation was for the hi-low system. Using the advanced omega 2 how would you use these charts to find good betting strategy? Since this is a level 2 count are the true counts double for your advantage and bet recomendations? Example if the chart says tc +2 is .90 ev and to bet 5 units, would tc+ for the ao2 need to be +4 for an ev of .90 and a 5 unit bet? Considering the ace side count is at neutral.
Thanks.
