just for curious, can you explain me how this house edge of 0.28% is calculed?
a little info there. but this is not the exact answer maybe. admin will come and answer you.

So in order to minimize the house edge, you should only place bets that meet the lifeline rules (so only small bets).
Seems like that. If someone win 3 bets with the help of life line then the house edge will be more lower. But that time luck is laso play a role. Lifeline is not mean you have 100% chance to win the bet.
And yeah I think it’s always happen that good players house edge is less than a normal/not good players imo. (I could be wrong though)
