HollyBlue, there are ways to increase the chance of 'getting lucky'. Yes, there are growers, but generally speaking charts indicate the bigger flaccid has a significantly better chance of becoming big upon erection. Here's info concerning that, plus other ways to increase the odds.
Length of Penis, Index Finger Correlated in Healthy Young Men

Oct. 3, 2002 — Men are often concerned about the adequacy of their external genitalia. To determine a basis on which to advise patients, investigators measured penile length and testicular volume in healthy young males and compared them with other body measures, as reported in the September issue of Urology.
"The lack of standardized metric data and the absence of widely acceptable criteria on the proper size of the external genitalia poses major difficulties in the counseling and/or treatment of young adult men with worries of sexual inadequacy," write Evangelos Spyropoulos, MD, PhD, and colleagues from the Naval and Veterans Hospital of Athens, Greece.
Somatometric parameters measured in physically normal men younger than age 40 years included tape measurements of penile dimensions in the flaccid-stretched state (total, shaft, glanular lengths), penile shaft volume calculation, and ultrasonographic testicular volume estimation. These values were tested for correlation with age, height, weight, body mass index, waist/hip ratio, and index finger length.
Mean testicular volume was 16.9 ± 4.7 cm3; total penile length, 12.18 ± 1.7 cm; penile shaft length, 7.76 ± 1.3 cm; glanular length, 4.4 ± 0.4 cm; and penile shaft volume, 46.5 ± 17.2 cm3. Although total, shaft, and glanular penile length were significantly correlated to index finger length (
P<.05) and to penile shaft volume (
P<.001), the authors recommend larger-scale studies involving more subjects to confirm this trend.
"The proposed mathematical formula...presumably could become a useful tool in the field of clinical evaluation of erectile dysfunction," the authors write. "Age and somatometric parameters were not associated with the size of the genitalia, excluding the index finger length, which correlated significantly with the dimensions of the flaccid, maximally stretched, penis."

BACKGROUND: In Nigeria, especially among the Igbo tribe, there is a well-held belief that a man's penile size can be predicted from his physique and the size of his buttocks, with people of small physique and flat buttocks likely to have long penile lengths. STUDY DESIGN: A prospective study to test the scientific veracity of this traditional and apparently mythical belief. Stretched penile length was measured in 115 men between the ages of 30-65 years and its correlation with the body-mass index and the circumference of the hip as measured around the most prominent points on their buttocks, was statistically determined. RESULT: The mean age of the subjects was 42.30 years (SD = 9.67), with a median of 40 years and a range of 30-65 years. The mean penile length was 13.37 cm with a median of 13 cm and a range of 7.5-19.5 cm. The mean circumference of the body around the buttocks was 96.46 cm (SD = 10.91), median 98 cm, and range 73-122 cm. The body-mass index ranged 17.34-44.44, with the mean at 26.87 (SD = 5.86), and the median 25.53. Linear regression statistics showed no statistically significant correlation between stretched penile length and body-mass index, thus physique. There was a significant direct correlation between penile length and gluteal size. CONCLUSION: The supposed relationship between penile length and gluteal size may have a scientific basis, but contrary to belief, large buttocks is more predictive of longer penile length than small buttocks. Penile length has no relationship to physique.

Height - The taller the guy the better chance there is he has a big one. Many don't believe a correlation between height and penis size exists, but this has been studied indepth at Thundersplace and there is somewhat of a connection. While the overall average size between tall and short guys is only 1/4" difference, the outliners (big and small dicks) showed a significantly higher occurance in relation to height. Tall guys twice as likely to have a big one.
Bulge - The bigger flaccids are more likely to be big when erect. Many don't believe there is any difference upon erection, but this has been studied indepth at Thundersplace and there is a correlation between flaccid and erect afterall. For instance, 3" flaccids were found to become 5.75" erect (overall generally speaking after erect numbers were added together and divided by number of guys), but 5" flaccids became 7.25" (generally speaking again). Some 3" flaccids can become bigger than some 5" flaccids upon erection, but the odds of becoming big are on the side of longer flaccids. Also, concerning the "grower" vs "shower" discussions that occur from time to time, in which so many seem to think everything equals out, notice that the 3" flaccids did grow more, closing the 2" flaccid gap (5" minus 3") by 1/2" making it a 1.50" difference (7.25" minus 5.75"). So there is some truth to the common belief that "growers" grow more than "showers", but it's mostly a false assumption as in general they do not catch up. Also, the longer dicks tend to have more girth, as the study indicates a strong correlation between length and girth, though of course once again there are plenty of exceptions and therefore no guarantees.
LPSG can't really be used to judge what the standard ranges of growing and shower are. Here is some data from yet another site (not ThundersPlace) several months back. I don't know if more has been added since then.

The numbers are somewhat unstable, which more data in each range would likely smooth out. The average increase is 2.5 inches in the chart above. The data above clearly shows that the belief shorter flaccids/growers are just as big as longer flaccids/showers when erect is a myth even though smaller flaccids tend to grow more (giving the myth some validity).
Also, another chart with several doctor studies concerning the relation between flaccid and erect size.

Thundersplace has studied shoe size vs dick size and found that the overall average is only slightly in favor of big feet (about 1/16 of an inch). However, a closer look into the detail reveals a real correlation afterall that exists in the outliner dick sizes. A shoe size of 12 (USA) and bigger shows twice as likely a chance of having an above average size penis than average size shoes.
