The first method is very accurate! They are 15 and 13, late bloomers, but tracking their current height and weight in conjunction with parental stats produces very accurate results. Only inputting parental stats is very inaccurate! My kids already surpass the predicted height based on just parental height. The kids are NOT an average of us.
It could have gone either way. Additionally, baby measurements are not a good predictor because of varying growth rates. My babies were tiny! Now, my 13 year old is in the 97th percentile. So, gauging them between is probably the most accurate. Put it like this: You know how a long- term forecast is not accurate? Short- term calculators predict the weather a day ahead. Which tends to be more accurate than the other forecast. Another reason why you might not end up at that height is because of your age.
This is because the further away your age is at from the point where you stop growing, it will be off by a a couple inches. For instance, if I have a balanced, consumed diet, then I would add an inch or two to my predicted adult height. Combined, I wouLd be very tall. If I was active, but did not have a good diet, then I would just add a couple inches only to my predicted adult height.

Her final growth spurt should occur roughly 2 years after her period has begun, and roughly 4 years after puberty has begun. You can think about it as genetics determining someone's maximum height, while their nutrition and other factors deciding if they get there or not.
