Remember, glidepath guidance has its apex or ending point centered on the official precision landing markings (what most people call the thousand footers). This is officially called the aimpoint. Large aircraft do not have much float when flaring. They both aim and touch down near the same point. 

Your little Cessna floats so much that your aim point and your touchdown point are not coincident. If you want to land on the thousand footers, you have to aim at the first touchdown marking (the five hundred footers). If you follow the VASI, PAPI, ILS or RNAV glideslope/glidepath all the way down to the ground, you will float past the thousand footers as soon as you enter ground effect.
