the amount of lines you play depends a lot on the payout.
If your 4/5 pays only $100 then you want to spend less but longer.
If your 4/5 pays $500 then you can afford to spend a little more each draw, or spend less and bet longer.
I spend on average $6 per draw. Which means I can go about three months losing before I am deep in the hole.
After 100 draws, thats $600 investment. Without a 4/5 win in that time, I mostly want to scream, pull out my hair and get a refund on my lottery products.
Luckily I am not panicking yet.
And no quick picks for me. (except for the ones I scan out at the vending machines)
