There can be differences in starting points of your observation, one of you could consider shrinking as a beginning of the process while another waited for the definite drop.

The melting of samples could have been performed very quickly so you or your partner was not able to see the precise melting temperature.

It could be a device error, instruments can be uncalibrated or calibrated differently.
