The altitude adjustment for Pretoria would generally be regarded as very slight (vs. sea level) for 100m. Pretoria is at around 1250m – which would make a difference (-.04-.06 for 100 and around a tenth for 200 and around .12-.15 for 300). Vs Ostrava at 250m.
So just the altitude would make the two times virtually equal.
