More on pronouncing "g's"....

[laepelba]

Before I ask my question, let's start with "ground rules" so that we're all using the same lingo. For the purposes of answering this question, let's say the following:
- when I say "hard g", I mean sounds like the word "agua"
- when I say "soft g", I mean sounds like the word "gente"

Now, on to my question....

I'm reading something about the pronunciation of the present indicative conjugations of the word "seguir". (sigo, sigues, sigue, seguimos, (seguís), siguen). The indication within this reading is that the "g" is pronounced differently in sigues, sigue and siguen. When I say "sigo", I use a hard "g" (like in "agua"). But I use the exact same sound for each of those six conjugations. Is that correct? Or are some of them pronounced differently?

Thanks!!
