Jaroslav, Nick, Chris et al.,
I agree that recording hits on a board of an acceptable standard size is probably the way to go, but for the purposes of discussion, this is what I would propose upon recording scores:
Whilst it is encouragibng the record a personal best of 5 or six hits, this would less accurately demonstrate the consistent level of ability than a running average.
On the face of it, this is a harder road to travel, but being less of a flatterer it is IMO a more useful tool in monitoring ones progress.
Say you were to shoot 16 "ends" of attempts at this target and scored, for the sake of argument, 0, 1, 0, 2, 1, 3, 2, 4, 3, 4, 6, 4, 3, 5, 1 & 4.
When these are shot does not matter so long as they are a true record of all ends shot.
This would be a running total of 43 divided by 16 sets which gives an average of 2.687 which would be more representative of your consistent level of ability than a claim of your personal best score of 6.
In this way, by keeping a simple card of all your attempts showing A. hits, B. total score/total sets, C. product of total score divided by total sets, you would be able to monitor any progress more truthfully.
If it was considered worthwhile as a motivating factor to publish scores for comparison, the running average and PB could be stated, since the object is to increase the average and to bring it closer to the PB, not to pretend that the PB repesents your consistent level of ability unless this can be supported by the running average.
I doubt that there would be an interest in ranking at the present time, but if this was of interest, I would suggest this:
First Class: Running average of 4.51 to 6.00
Second Class: Running average of 2.51 to 4.50
Third Class: Running average of 0.10 to 2.50
This makes Third Class readily achievable, Second Class not impossible and retains First Class as requiring some considerable effort, as it should be if it were to be meaningful as a distinction.
I would make no distinction in draw weight except to post a minimum acceptable. Beyond this you choose the draw weight you think that you can command.
If time and experience shows otherwise, you have a choice to make.
This might seem daunting, but it is a useful tool in helping to form a true picture of your own level of consistent ability in this particular area of shooting.
At the end of the day, you will know your draw weight, how far you can shoot and your rate of fire.
The premise is that it is helpful to also know your standard of accuracy.
Knowing it, you can then if you choose, work upon improvement.
Not knowing it, what can you honestly do?
If you can hold a group at 100, you will be the more accurate at your longest distance.
