Re: [FTC]:Finding weighted rings vs regular rings

That’s four cycles, or round-trips, for the two robots. Finding weighted rings and hanging them adds cycles.

Your strategy then depends on how reliable your autonomous is, your cycle time, how quickly you can identify a weighted ring and your assumptions about your partner’s autonomous and cycle time. Remember, to avoid wasting time and the bottleneck at the dispenser, one of the robots will need to use the far dispenser.
--NOTE THIS ANALYSIS ASSUMES NO AUTONOMOUS SCORED --
Now you are describing the reality of the game that I was talking about.
We plan to place two rings on each of the 2nd level scoring pegs initially.
The fourth cycle we will use this next ring pair to place one of them each on the upper and lower of one side or the other side.

This approach means that starting after the second cycle, every trip can earn at least 30 point row bonus plus 20 more for the level scoring. The fourth cycle can also earn a 30 point row bonus with 20 ring scoring, and if a 5th cycle can be done, 20 for level scoring and 90 points of row bonus -- 110 in one cycle!!

So we see it as critical to get at least four scoring cycles completed. Only a trip to the corner with at least 125 points already scored and two heavy rings can give a 50 or more points of heavy ring bonus, but if it jeopardizes us from completing the forth scoring cycle, and prevents us from even being able to attempt a 5th cycle, then it is barely worth the 50 points loss that the fourth scoring cycle would have generated, and it totally kills the possibility that getting a 5th cycle at 110 points can even be attempted. So we see going for the heavy ring scoring as a sucker deal.

In the early portion of the match, we also don't want to waste time shuffling heavy rings between pipes to try and arrange to get a pair of heavies adjacent either. It is just too critical to complete the initial scoring cycles done to have access to the possibility or reaching the stage where every additional cycle can give 5o to 90 points of row bonus.
