[QUOTE="bigag03, post: 826102, member: 9247"] Whether the program is TPR or THR or whatever your particular breed association calls it, these programs were designed to increase the accuracy of data that is used for EPD calculations. If the honor system worked, then I am sure that all of these NON-PROFIT breed associations would find a better way to structure the program. At the end of the day, the only way to get anyone to do what is necessary is to hit them in the pocketbook. Example: (with easy math, don't analyze the actual numbers) You have 10 registered calves 5 with WW of 475 lbs, 2 with WW of 520 lbs, 1 with WW of 525 lbs, 2 with WW of 530 lbs (overall average of 500 lbs). On the old system, you cull the 5 calves below 500 lbs and only register the 5 over 500 lbs, but by doing that now, your 520 lb calves are 5 lbs below average even though they are better calves. Because of this, their EPD calculations are incorrect because the number that holds the largest weight in EPD calculation is the ratio within a contemporary group. In the new system, you still cull the 5 calves below 500 lbs, but you turn in data on all of them because you have already paid for it. By doing this, now your 520 lb calves (your "worst" calves left) have a ratio that reflects that they are 20 lbs above average and their EPDs reflect this performance. The only way to have reliable EPDs is to turn in ALL data. Recommend a better solution to collecting this data or quit complaining about the current system. [/QUOTE]
