Calculation of 3Y and 5Y annualized return date lag

[mf12ca]

The date lag for the calculation of 3Y and 5Y annualized return is based on 35 and 59 months, respectively.
This should be years=3/5 (or months=36/60) instead:

Current code:
d = today - relativedelta(months=35)
metrics["3Y (ann.) %"] = _stats.cagr(df[df.index >= d], 0.0, compounded) * pct

d = today - relativedelta(months=59)
metrics["5Y (ann.) %"] = _stats.cagr(df[df.index >= d], 0.0, compounded) * pct
