To create a proportional scale for a maximum of 82 initial points, we can calculate the ratio of final points to initial points based on the given data.

Letâ€™s calculate the ratio for each data point:

For 7 initial points, the ratio is 8/7 = 1.1429. For 12 initial points, the ratio is 15/12 = 1.25. For 38 initial points, the ratio is 43/38 = 1.1316. For 54 initial points, the ratio is 60/54 = 1.1111. For 68 initial points, the ratio is 75/68 = 1.1029. For 83 initial points, the ratio is 94/83 = 1.1325. For 86 initial points, the ratio is 100/86 = 1.1628.

Now, we can use these ratios to calculate the final points for each initial point from 1 to 82:

For 1 initial point, the final points would be 1.1429. For 2 initial points, the final points would be 2 * 1.1429 = 2.2857. For 3 initial points, the final points would be 3 * 1.1429 = 3.4286. â€¦ For 82 initial points, the final points would be 82 * 1.1628 = 95.2256.

Please note that these values are rounded to four decimal places.
