this is an "easy" one
she has such beautifully consistent times, it's a pleasure to work with such numbers !!!

gives her 1.5 - 5k pbs all set last year as :
4'05.86, 8'33.25i ( probably worth a coupla seconds quicker outdoors ) & 14'44.80
trying various combos of these for her potential 10k time last year :
4'05.86 / 8'33.25 -> 30'35.5
4'05.86 / 14'44.80 -> 30'44.75
8'33.25 / 14'44.80 -> 30'49.4
too wide a range here because 3k is an indoor time & the 5k looks a little weak
after a coupla minutes trying out different times, her best line of fit with most fundamental of times : 400m & 800m suggests last year she was in :
~ 1'00.0 / 2'05.6 shape which ->
~ 4'05.1 , 8'31.1 , 14'37.6 , 30'25.1
this is last year's news, but i'm confident that 30'25 was her limit then off her 15.k - 5k training
if she has a very, very accurate idea of her current 400 & 800m ability ( to within 0.1s auto ), we'd have a very good idea of her 1.5 - 10k potential this year
