I challenge you to show me a Reno or CUBIC based connection's cwnd evolution that *doesn't* resemble a sawtooth, regardless of the congestion signalling employed.  And I will show you that it either has severe underutilisation of the link, or is using SCE signals.  The sawtooth is characteristic of the AIMD congestion control algorithm.
