Having started the thread and now read some of the replies I would now like to make some positive observations:-
1. In my opinion part of the challenge of ESK is that the weather plays an important part, the fact that the targets aren't always the same depending on the conditions contributes to the skill required. Therefore changing the speed to make the targets fly truer in poor weather actually is backward step. I make sure I practice in all weathers so that if it comes to a competition and the weather is poor I have the experience.
2. Some people may not shoot skeet because they perceive it to be
a) Easy - not true in my opinion it takes practice and the goals are different to say sporting or trap, my goals are something like shoot 50 straight, shoot 75 straight, score more than 90 in a major, win my class on a local shoot. All these are achievable without saying "I must get 100 that is the only goal"
B) Boring - not true in my opinion it is a different discipline and therefore requires a different skill set, the biggest one I have found is keeping my concentration over a complete 100 bird shoot.
So my ideas for encouraging more skeet shooting would be along the following lines
a) Taster and introduction days at local grounds, in my experience most regular skeet shooters are more than happy to help new skeet shooters with their first try
B) why not have 50 bird registered comps (they do in sporting) this would enable newer skeet shooters to experience competition without the full cost of a 100 bird shoot
c) Promote local skeet competitions more in PULL both before they occur and after with results, write ups etc, you often see reviews of sporting comps but hardly ever skeet comps
d) encourage juniors and colts to take up skeet, even if their main discipline is sporting, skeet helps with hold and look point discipline which is just as relevant to sporting as skeet and many seasoned sporting shooters often "warm up" with a couple of rounds of skeet first
e) Promote skeet competitions to local ground owners if they have the facilities, it only takes 1-4 referees for a skeet competition as opposed to 10-15 for sporting so the economics for them are appealing
I am sure there are many more good ideas out there without having to mess about with target speed etc.
