Casino bonus question

[Jim Morgan]

On another forum, someone said that you can get a higher EV by playing standard bonuses as if they were a sticky bonus.

When I try to duplicate such a claim, I find the EV is unaffected. For example, if I get a $100 bonus on a $100 deposit with a total WR of 2000, I can flat bet BJ and get an expectation of $100 - HA. (house advantage)

If I choose to treat it like a sticky and make $25 until I bust or reach $400, my expectation is 0.5 * 300 - 0.5 * 100
= $100. Once again we need to subtract HA.

I do see this as being an improvment in 2 ways. First, if I bust out the bonus, I will be done a lot faster. If I reach my target, I will finish up with small bets and pay the same overall HA. However, doing this twice will rate to save me a few bucks and some time, assuming 1 win and one loss.

Are there other advantages to using a "sticky" strategy for a standard type bonus?

Is this strategy also better for "cover", or does the switch to small bets at a target make it actually easier to be marked as a bonus player?
