Has the problem caused by poorer precision in the original daily temperature data been solved

[PanfengZhang]

Recently, I read a paper titled "The influences of data precision on the calculation of temperature percentile indices" (Zhang et al.2009). The paper showed that when the data precision is insufficient, it will affects the estimation of means and trends of percentile-based indices. And, in this paper, it claimed that "... we have updated RClimDex to eliminate the problem caused by poorer precision in the original daily temperature data" (Page 6). I want to konw if this problem has been solved in the R package climdex.pcic ?
Thank you.
