Being new to the group, I hesitate to make suggestions about the game,
Certainly you shouldn't hesitate to make suggestions or voice concerns about anything you don't agree with. How old your hands are have no bearing on the value of your opinion. No MVL members opinion is any more valid or valuable than any other MVL member.
But basically this point was the subject of a league wide vote in which the suggestion you're making was one of the listed options (specifically #3). See the MVL Tiebreak Criteria Vote
thread at the Core.
I do probably need to point out that the choice that was selected by the vote (#4) doesn't explictily mention the case of what is done if both speed and score were tied but suffice to say there was significant discussion about this very issue and it was explictly stated elsewhere that this option would leave items tied by both speed and score with each receiving the full value of the bonus. It could be stated that no one honestly believed that such an occurance would ever happen but it was discussed and this is how the rule is written up in the rules thread.
Clearly we can revisit this if necessary, though probably the rules thread is the better place to do it if you still feel strongly about it. Certainly anyone is free to suggest anything they want but per our newly ratified voting rules someone would need to propose an alternative to the current rule and make a motion that would need to be seconded by two other MVL members before it could be brought to a vote.
I'm sure if there are others that agree with you then they will mention their support, but I prefer the idea that everyone that deserves a bonus gets the same bonus.
Your proposal is similar to the more standard policy of awarding 3, 2 and 1 points for 1st, 2nd, and 3rd. We initially had such a scheme but felt that was too much emphasis on individuals as opposed to teams.
I would tend to hope that you don't jump off a pier because of this except that it might actually be fun. But what exactly is a "pleasure" pier, I'm curious?
