Speaking from personal experience the answer is yes.

After making some of my own systems I can vouch for the fact that some were hopeless some were good and a few were very good.

Obviously the very good ones were better than the hopeless ones.

Every once in a while, a dozen or two of the same double streets will sleep for 30 consecutive spins in a row.

Check this out: bet 100 on the high 18, (19-36). Bet 25 on two of the three double streets from the low 18, (1-18). If you get a high 18 spin then you get 50. If you get one of the low 18 double streets then you break even. If you get the one double street without a bet then you lose 150, same for zero.

Hello mr. gizmotron
Can I ask what is the use of this bet? I can see it is a solid break even bet, and that means the only advantage to come will be in a streak of the high 18, but at those times wouldn't you be best to simply bet the high 18? I don't understand the arrangement.
